a shallow person usually who likes to judge other people's looks yet are oblivious to their own flaws. they hang out in big groups and like to start shit with total strangers and resort to sterotypes to try to piss off strangers. they have like no real taste and like to use deogroaty terms to piss you off. they also hang out all day at mall doing nothing and purposely trying to provoke a fight with total strangers.

total stranger : "excuse me? fucking mallrat! you shouldn't talk you look like total trash and your're fucking ugly inside and out"
