AI & tech-bro slang

The post-ChatGPT tech industry moves fast enough that its vocabulary turns over every six months. Some of these terms are precise technical jargon (RAG, hallucination, prompt-injection); some are joke-words minted on Hacker News and X that escaped into wider use (vibe coding, AI slop, brainrot).

This is Slangora's catalogue of AI and tech-bro slang from roughly 2022 onward. It captures both the serious (engineering shorthand) and the satirical (the meme-vocabulary critiquing the same engineering).

Bottom line

Half this vocabulary is real terminology being born in real time. The other half is the discourse making fun of the first half. Both belong in the dictionary.
