How Internet Slang Went From Chat Rooms to the Oxford Dictionary
Published 2026-07-27
The history of internet slang is also the history of how humans adapted language to new technology , and how quickly that adaptation happened. What took decades in the early internet now takes days. Here's the full arc, from the first online abbreviations to the algorithm-powered vocabulary explosion of today.
The beginning: bulletin boards and early chat (1980s-90s)
The first internet slang emerged from necessity. Early online communication was slow, expensive by the minute, and typed on awkward keyboards. Abbreviations saved time and money. LOL (laughing out loud), BRB (be right back), AFK (away from keyboard), and IMO (in my opinion) all date to this era , some appearing as early as the mid-1980s on bulletin board systems.
This was functional slang with no cultural agenda. Nobody was performing for an audience or signaling group membership. The keyboard was just inefficient and brevity was practical. The style is still with us: ASAP, FYI, and dozens of others began here and never left.
The chat room era (late 90s - early 2000s)
AOL Instant Messenger, IRC, and early chat rooms brought slang its first social dimension. Now abbreviations weren't just practical , they were cool. Knowing the vocabulary marked you as someone who belonged online. "A/S/L" (age, sex, location), "ROFL" (rolling on the floor laughing), and the emoticon family :) :( ;) emerged in this period.
Gaming communities in this era also began developing their own vocabulary. "Noob" (new or unskilled player), "GG" (good game), and "pwned" (defeated decisively) all have roots in late-90s gaming. Several of these survived and entered general use decades later.
Social media changes everything (2000s-2010s)
Facebook, Twitter, and YouTube created something new: public audiences for informal language. Slang that previously circulated in closed communities now had exponential distribution potential. A term that caught fire on Twitter could reach millions in days.
This era produced some of the most durable slang in current use. "Fail" as a standalone exclamation, "epic," "troll," "meme" itself as a concept, and "viral" as a descriptor for content all became part of mainstream vocabulary through this period. The pipeline from niche community to mainstream was established and it never stopped accelerating.
The TikTok acceleration (2016-present)
Short-form video changed slang forever by adding voice, personality, and algorithm to the mix. A creator saying a word on camera , with the specific intonation and context that makes slang work , could reach 50 million people. The algorithm then made sure the most engaging content traveled furthest.
This is where rizz came from: one streamer's verbal habit amplified by millions of viewers and billions of algorithm-driven views. It's where delulu escaped K-pop fandom into general use, where brain rot became Oxford's Word of the Year in 2024, and where skibidi went from a bizarre YouTube cartoon to every playground in every country.
The Oxford moment
The clearest sign that internet slang had permanently entered the mainstream came in consecutive years: Oxford named "rizz" its Word of the Year in 2023 and "brain rot" its Word of the Year in 2024. Both words originated in online youth culture and both were chosen specifically because they captured something true about contemporary life that no existing word did as well.
This is the test that determines which slang survives: does it fill a gap that existing vocabulary leaves open? Rizz (effortless charm in romantic contexts) and brain rot (the mental effect of low-quality internet content) both do. The words that don't fill genuine gaps , the purely absurdist ones, the catchphrases , have shorter lives.
What comes next
The pipeline will keep accelerating. AI-generated content is already creating new vocabulary pressures , words like "algospeak" (vocabulary invented to evade content moderation algorithms) represent a genuinely new category of slang that has no historical parallel. And the generation growing up now (Gen Alpha, born roughly 2010-2025) is developing vocabulary at a pace and scale that researchers are still trying to measure.
The only reliable approach, as always, is curiosity and a good reference. Our dictionary tracks the terms as they emerge, and our blog covers the stories behind where they come from. Language is always moving , we just try to keep the map current.
