Introduction

TL;DR

Merriam-Webster designated “slop”—defined as “digital content of low quality that is produced usually in quantity by means of artificial intelligence”—as its 2025 Word of the Year, announced on December 15, 2025[1][4]. The selection captures a pivotal shift in how society perceives artificial intelligence: from fear-driven discourse to critical mockery of AI’s creative inadequacies. The widespread proliferation of low-quality AI-generated content across the internet sparked broader social discourse around AI ethics, content verification, and digital trust. Notably, other major dictionaries also selected AI-related terms for 2025—Oxford chose “rage bait,” Macquarie selected “AI slop,” and Cambridge added “slop” alongside its primary selection of “parasocial”—signaling a global recognition of this phenomenon’s cultural significance[21][24].

Why it matters: The term ‘slop’ represents more than linguistic innovation; it marks the moment when digital culture became conscious of content saturation and demanded higher standards for online information. This shift has cascading implications for content governance, algorithmic accountability, and the future of digital marketplaces.

The Evolution and Definition of ‘Slop’

Historical Context

The word “slop” originated in the 1700s to denote soft mud, evolved in the 1800s to mean food waste (particularly pig feed), and gradually broadened to signify anything worthless or valueless[10][26]. In 2025, the digital age has gifted this word a precise, contemporary meaning that perfectly encapsulates a specific technological phenomenon[2][5].

According to Merriam-Webster’s definition, slop is “digital content of inferior quality that is typically produced en masse by artificial intelligence.” This characterization emerged as AI systems, particularly large language models and image diffusion generators, accelerated the creation of high-volume but low-quality written and visual content[2][5].

Peter Sokolowski, Merriam-Webster’s Editor-at-Large, observed that in 2025, amid discussions of AI threats, “slop set a tone that’s less fearful, more mocking. It’s almost like the word sends a little message to AI: when it comes to replacing human creativity, sometimes you don’t seem too superintelligent”[4][29]. This commentary reveals a fundamental shift in cultural discourse—from apocalyptic warnings about AI replacing humans to critical, sardonic evaluation of AI’s actual creative capacity[1][26].

The Origin and Adoption of the Term

The term “slop” as applied to low-grade AI material emerged around 2022, following the release of AI image generators[2]. Early usage appeared among technical communities on platforms like 4chan, Hacker News, and YouTube, functioning initially as in-group slang[2]. British computer programmer Simon Willison is credited with championing “slop” in mainstream discourse via his personal blog in May 2024, though he acknowledged the term’s earlier underground circulation[2].

Broader adoption accelerated in Q2 2024, particularly following Google’s deployment of its Gemini AI model to generate search responses, combined with widespread criticism of AI-generated content flooding the internet in Q4 2024[2].

Why it matters: The linguistic trajectory of “slop”—from underground technical jargon to dictionary-enshrined cultural marker—mirrors the speed and scale of AI’s integration into daily digital life. The rapidity of this adoption suggests society required urgent terminology to process and critique an unprecedented phenomenon[2][5].

The Landscape of ‘Slop’ in 2025

Manifestations of AI-Generated Content

Throughout 2025, Merriam-Webster documented concrete examples of slop that saturated digital spaces: absurd videos, distorted advertising imagery, cheesy propaganda, convincingly fabricated news, poorly crafted AI-generated literature, “workslop” reports that waste colleagues’ time, and countless videos of talking cats[1][4][26]. These materials share a common DNA: they prioritize velocity and volume over substantive value, accuracy, or authentic creativity[2][3][8].

The problem intensified in the first half of 2025 when Google’s integration of Gemini AI into search results produced a visible deluge of slop, demonstrating how even major technology platforms struggled to curate quality from AI-generated alternatives[2].

Core Problems with AI-Generated Content

Absence of Genuine Creativity: AI systems are trained on pre-existing, pre-published content and cannot generate truly original ideas or forge novel connections between concepts[12]. Over time, as AI models retrain on AI-generated content published to the internet, the quality degrades in a vicious cycle[2][5].

Quality Degradation: AI-generated text is typically generic, unoriginal, and devoid of personality[12]. AI-generated images frequently display pixelation, blurred hands, and missing image sections—artifacts that misrepresent reality in an age when advanced multimedia production is accessible[12].

Model Collapse: Research demonstrates that training large language models on slop produces measurable degradation in lexical, syntactic, and semantic diversity, particularly affecting tasks requiring high creativity[5]. When AI content undergoes repeated refinement, paraphrasing, and reprocessing, information gradually distorts—similar to the childhood “telephone game,” where messages become increasingly corrupted through serial transmission[5].

Hallucination and Fabrication: AI generates plausible-sounding but fabricated information, including invented references and fake citations[9]. Medical organizations have been documented publishing AI-generated content on specific drug dosages and medical advice without human oversight or disclosure to clients[15].

Information Decay Through Iteration: When identical content is continuously refined through successive LLM iterations, information distortion accumulates. Research shows this phenomenon mirrors classical communication breakdown patterns[5].

Why it matters: These technical failures translate to practical societal harms: eroded trust in digital information, copyright violations, financial losses for legitimate creators, and degraded user experience across platforms. The quality problem is not a temporary growing pain but a structural consequence of current AI deployment models[2][12].

The Threat Landscape: Misinformation, Deepfakes, and Exploitation

Deepfakes as Fraud Infrastructure

Consumer Reports research from 2025 documents how AI deepfake technology now powers scams, fraudulent schemes, non-consensual intimate imagery, and coordinated misinformation campaigns[13]. The research reveals a troubling finding: consumers struggle to identify deepfake videos as false while simultaneously overestimating their own detection abilities[13].

Investment Fraud Case Study: One consumer was defrauded of $690,000 after viewing a deepfaked video of Elon Musk endorsing an investment opportunity[13]. The incident exemplifies how convincing AI video synthesis has become and how vulnerable even educated audiences remain.

Voice Cloning and Impersonation: AI voice cloning enables scalable impersonation fraud, including “grandparent scams” where perpetrators contact victims impersonating distressed family members. These tools reduce labor previously required for deceptive practices while opening new attack vectors entirely[13].

Spear Phishing Automation: AI enables automation of previously labor-intensive spear-phishing attacks—personalized phishing messages calibrated to individual targets—at unprecedented scale[13].

International Response and Risk Assessment

The United Nations’ International Telecommunication Union (ITU) released a report in July 2025 emphasizing that businesses must employ sophisticated detection technologies to identify and eliminate misinformation and deepfake content to mitigate escalating threats of electoral manipulation and financial fraud[19].

Corporate vulnerability is acute: a 2025 executive survey found that eight in ten leaders express concern about AI-driven misinformation impacting their brand—yet many admit their organizations lack adequate readiness to detect or respond to such threats[16].

Intellectual Property and Creator Economy Disruption

AI systems scrape and appropriate content from public sources, depriving human creators of their work’s value while substituting AI-generated slop of dubious provenance[13]. This practice raises cascading legal issues: copyright infringement, data privacy violations, and exploitation of creative labor without consent or compensation[13].

Why it matters: The convergence of deepfake technology, misinformation infrastructure, and intellectual property violations represents not isolated technical problems but a systemic threat to information authenticity, financial stability, and democratic processes. Solutions require coordinated action across technology, regulation, and user education[13][19].

Global Dictionary Consensus: AI Dominates 2025 Linguistic Markers

The selection of ‘slop’ was not Merriam-Webster’s isolated decision but part of a remarkable global consensus: major dictionaries across English-speaking regions selected AI-related terms to define 2025[21][24].

Comparative Word Selections

Merriam-Webster: “Slop” Definition: Digital content of low quality produced in quantity by artificial intelligence[1][4]. Selection methodology: Analysis of search volume spikes on Merriam-Webster.com[4].

Oxford University Press: “Rage Bait” Definition: Online content deliberately designed to elicit anger or outrage through frustrating, provocative, or offensive material, typically posted to increase traffic or engagement[30][29]. Selection methodology: Three-day public voting involving over 30,000 participants combined with expert analysis[24][29].

Macquarie Dictionary (Australian English): “AI slop” Definition: Low-quality content created by generative AI, often containing errors, typically unrequested[24]. The committee’s commentary was particularly incisive: “We understand now in 2025 what we mean by slop—AI generated slop, which lacks meaningful content or use. While in recent years we’ve learnt to become search engineers to find meaningful information, we now need to become prompt engineers in order to wade through the AI slop”[24].

Cambridge Dictionary: “Parasocial” Definition: Involvement or relation to a one-sided connection someone feels between themselves and a famous person they do not know, a book/film character, or artificial intelligence[22][28]. Notably, Cambridge added or updated multiple AI-related terms in 2025, including a formal inclusion of “slop” defined as content on the internet of very low quality, especially when created by AI[22].

Collins Dictionary: “Vibe Coding” Definition: The use of artificial intelligence prompted by natural language to assist in writing computer code—essentially, telling a machine what you want rather than manually coding it[24]. This selection reflects AI’s more productive applications.

Dictionary.com: “67” A numerical selection pronounced “six-seven,” potentially meaning “so-so” or expressing ambivalence, particularly among younger users[24][26]. This choice reflects generational skepticism regarding AI and technological advancement.

Significance of Consensus

The coordinated selection of AI-related terms across major dictionaries demonstrates the phenomenon’s pervasiveness and cultural penetration[21][24]. Unlike past years when dictionary choices diverged widely, 2025 revealed broad agreement that artificial intelligence—specifically its implications for content quality, digital behavior, and human interaction—constitutes the year’s defining concern[21][24].

Why it matters: When independent linguistic authorities reach consensus on a topic’s cultural significance, it signals that concern has transcended niche expertise to become genuinely mainstream. This democratization of discourse makes AI accountability a public expectation rather than a specialist concern[21][24].

Emerging Frameworks: AI Ethics and Content Governance

The E-E-A-T Paradigm

Google’s E-E-A-T framework—Experience, Expertise, Authoritativeness, Trustworthiness—has become the benchmark for distinguishing quality content from slop[6][14]. High-quality content derives from human experience, substantive expertise, authoritative sources, and demonstrated trustworthiness. This principle stands in stark contrast to generic, attributionless AI-generated content[6][14].

Organizations increasingly recognize that AI cannot be deployed without governance structures. The industry consensus of 2025 is unequivocal: “AI should complement, not replace, human creativity”[3][6][14].

Best Practice Governance Architecture

Successful AI content strategies implement multi-layered human oversight:

Multi-Stage Review Process: Human reviewers engage at critical junctures throughout content creation, not merely at publication[3][6].

Fact Verification: All data, statistics, and citations undergo validation against credible primary sources[6][14].

Brand Voice Preservation: AI handles structural drafting and ideation; humans infuse tone, personality, values, and strategic alignment[6][14].

Bias Detection and Mitigation: Advanced algorithms scan content for potential demographic, cultural, and ideological biases before publication[3][14].

Transparency and Disclosure: Organizations clearly communicate AI’s role in content creation, building rather than eroding audience trust[3][6][14].

Continuous Monitoring: Regular audits ensure published content meets ethical standards and quality benchmarks[17].

Institutional Governance Mechanisms

Forward-thinking enterprises implement content governance frameworks—tools like Acrolinx establish automated quality gates, preventing non-compliant or off-brand content from publication while maintaining compliance, consistency, and brand integrity at scale[14]. These systems recognize that human oversight, while essential, cannot scale to match AI’s production velocity; therefore, governance automation becomes necessary infrastructure[14].

The 90% Figure

Industry analysis suggests that by the end of 2025, approximately 90% of internet content will involve some degree of AI assistance[3]. This projection underscores the impossibility of “rejecting” AI; instead, the challenge becomes governing it responsibly.

Why it matters: The emergence of governance frameworks represents a maturation of AI deployment from “let’s see what’s possible” to “how do we maintain human values while scaling production.” This transition mirrors industrial governance evolution and suggests AI integration requires institutional discipline comparable to finance, healthcare, or pharmaceuticals[3][6][14].

Technological Countermeasures: Detection and Accountability

The Detection Revolution of 2025

A remarkable reversal occurred in 2025: AI content detection technology surpassed AI generation capability[15]. Multiple independent detection tools now identify AI-written content with near-perfect accuracy rates—including outputs from the most advanced models: GPT-4o, Gemini Flash, and Claude 3.5[15].

2023 vs. 2025 Comparison:

  • 2023: AI tools could occasionally evade detection; detection remained probabilistic
  • 2025: Public-access detection tools achieve approximately 100% accuracy across nearly all AI writing platforms[15]

This technical reality has profound implications. As one researcher noted: “If it’s written by a machine, it can be detected by a machine. And that’s never going to change”[15].

Institutional Detection Integration

Given these advances, integration of AI detection into email spam filters (Google’s system is dominant) and social media content moderation appears imminent[15]. This would mean AI-generated content automatically routed to spam, shadow-banned, or deprioritized—rendering slop’s profitability model unsustainable[15].

The March 2024 Precedent

Google signaled its position as early as March 2024 when algorithm adjustments penalized low-quality, manipulative content. The penalty underscores that dependence on AI-generated content for SEO represents an uncontrolled risk[15].

Why it matters: Detection superiority suggests slop’s dominance may prove temporary. However, the interval between detection capability and institutional deployment remains uncertain—creating a window during which malicious actors can exploit advanced generative capabilities before detection becomes ubiquitous[15].

Conclusion: Establishing Digital Literacy in the Age of Slop

The selection of “slop” as Merriam-Webster’s 2025 Word of the Year transcends linguistic observation to reflect a civilization-scale recalibration of how society engages with artificial intelligence[1][4][26].

The central insight is unambiguous: AI is a powerful tool, but society must maintain critical distance from the low-quality content it generates at scale[1][26].

Transitioning from technological optimism toward pragmatic evaluation, contemporary society now demands[1][3][6][14]:

  1. Institutionalization of AI Ethics: Clear corporate codes of conduct for AI deployment
  2. Reinforced Content Verification Systems: Multi-stage human oversight, fact-checking, bias detection
  3. Transparency Principles: Public disclosure of who employs AI, how, and why
  4. Creator Protection: Copyright enforcement, data security, and intellectual property rights
  5. Digital Literacy Enhancement: User capability to distinguish authentic information from slop

The 2025 term “slop” need not represent cultural decline—rather, it can mark the inflection point toward more robust digital governance. The technology itself is not the enemy; the abdication of human values and accountability is[1][3][14][26].

The task before institutions, platforms, and individuals is not to reject artificial intelligence but to integrate it under frameworks that preserve human agency, creativity, and trustworthiness[3][6][14]. The future will not be determined by whether AI exists in our information ecosystem—it will be—but by whether humans maintain responsibility for its governance and consequences.
