An LLM check is the act of running something past an AI language model to verify, fact-check, summarize, or improve it before trusting or using it — the 2020s equivalent of Googling something, but more conversational and more prone to confident-sounding errors.

A hallucination check is the moment — increasingly necessary in the age of AI-generated content — when someone pauses to verify whether what they just read, heard, or received actually reflects reality. Borrowed from the technical AI term for when large language models confidently produce false information, the hallucination check has migrated into everyday slang to describe any reality audit: fact-checking a hot take, googling a citation that sounds slightly too convenient, or just asking 'wait, did that actually happen?' The term carries a mild paranoia that feels appropriate for a media environment where plausible-sounding nonsense travels fast.
A call-out or prompt asking someone to acknowledge that they took a loss — either in an argument, a situation, a decision, or life in general. Dropping an L check on someone is a way of formally presenting evidence of their failure and requesting a receipt. It's confrontational but usually playful, delivered alongside screenshots, receipts, or simply a knowing look. The person being L checked is expected to admit the L or face escalating mockery. Not taking your L gracefully after an L check is itself an L.
Someone who has fully swallowed the AI hype and now sees large language models as the solution to every problem — personal, professional, existential. LLM-pilled people automate their grocery lists, therapy journaling, and first dates. They cite token counts in casual conversation and get mildly offended when you say you still Google things. It's not quite a cult, but they will absolutely send you a custom GPT you didn't ask for.
An LLM check is the act of running something past an AI language model to verify, fact-check, summarize, or improve it before trusting or using it — the 2020s equivalent of Googling something, but more conversational and more prone to confident-sounding errors. When someone says they're doing an LLM check, they're acknowledging both the utility and the skepticism: the model might be right, or it might be hallucinating with complete conviction. LLM checks have become a reflex for students, writers, and professionals navigating a world where AI assistance is ubiquitous.
Hold on, let me do a quick LLM check on this legal clause before we sign anything.
