1. An asshole who is very intelligent but likes to piss people off by acting retarded. Usually hated by everyone. Extremely fucking annoying.

2. The annoying son of a bitch who sits behind you and makes some fucking weird noise and kicks your chair, and then turns around and gets an A+ on some Calculus test and then rubs it in.
The smart dumbfuck got a fucking 4.0 and he still acts like a fucking retard. I hate that son of a bitch.
