fa cai
A total loser who smells like old socks and thinks they're the king of the world. They might be a faggit, a douchebag, or just some random shady mofo causing trouble.
You’re the worst, fa cai. I’ve seen dogs with better taste.
Why are you still here? You’re like a fa cai in a room full of winners.
That guy at the bus stop? Total fa cai. He said he was a rockstar.
