Also called "sub", the poor person, either fresh out of college or old and retired, who fills in for absent teachers. The sub can expect to be ridiculed and tortured by bitch-ass 7th graders who will do anything in their power not to finish an easy worksheet left them by their teacher. The sub is basically a $55/day babysitter.
Bitch-ass kid: Ah hell yeah we got a substitute today! We ain't doin shit! Hey Mister, uhh...Mister!(kid can't read last name on the board because he's an illiterate degenerate) Can I go to da bafroom?
