Short for legitimate. If something’s legit, it’s the real deal, not fake, not scammy, and not just your mate overhyping it. People also use it as an intensifier, like I’m legit starving or that was legit wild. Works in speech, texts, and reviews, so it’s basically slang duct tape. You’ll hear it everywhere from corner stores to group chats.
"This slice is legit, deadass. I was ready to call it hype, but now I’m guarding my box on the subway like it’s gold."
