Gavin 

A son of a bitch that is both a dumbass and good at math at the same time. He will never put a hat on for some reason because he doesn't want to mess up his "perfect" hair. Buys all the new skins and emotes in Fortnite even though he only has 4 solo wins. He tries to rap but it just comes out as a compliment.

Guy: That guy is such a Gavin! He's in AP Calculus but can't tell the difference between a roast and a compliment
Girl: Well, forget that libtard
