a lot of online (which is where gen z stuff comes from) culture is just black american culture, it's not particularly different from how most european languages have a bunch of french loan words.
Hmm, looks like it has been used by a variety of people for a while. This is what I could find, but if you have a better source for that claim, I am open to correction.
"This guy's cooked." (He's had too much/he's out of it/he's screwed)
"I'm cooked, chat." (I'm out of options/it's over for me)
In the context of this meme, which is from the movie Back to the Future, Marty is in the past and using slang that hasn't entered popular use yet, so Doc thinks he's talking about cooking food and is confused about what he means.
Also not to be confused with similar "Let them cook" (they're onto something, let's see where this goes).
Aussie slang. Started as people who were cooked ie: fried their brains (could be drugs, more commonly nowadays brainrot from conspiratorial internet influences) , extends to other situations and a euphemism for "fucked"
UD is heavensent for people like me who have to use YT channels like Lessons in Meme Culture (LIMC) to keep up with the kids, but have typically no idea what the new slang means.
It's already time for "cooked" to be back in rotation again? Are kids just learning how to be cool from their parents now? Hell, not even, that one was last up no more than a decade ago.
What's next, the "-izzle" phase again?
If you're gonna bring something back, ressurect some of the old lost classics; like bodacious, gnarly, and groovy. Sick, cram, hip, mod, tubular, cranking... These have all been to rest long enough to come back before cooked.
