A college kid who thinks he's better than everyone else because he is in a fraternity
. Some college kids are frat boys even though they aren't in a fraternity. Frat boy behaviour is typified by drinking shitty beer, hitting on high school girls, making fun of punks, and wearing boring clothes.
Dude, these fucking frat boys came to the show at Bernie's
the other night, and they started some shit, but my dudes and I kicked their bitch asses.
