One who overcompensates for his/her/it's insecurities (i.e. being fat, or having a small penis) by being overtly cocky, aggressive, or aggressively defensive.
You see that fat f***, Jake over there? He just told that fine honey that he wants to f*** her in the bathroom. OH SHI*! She just called him a fatass and he ripped her in half and is now defecating in her internal organs! Man, that kid is such a starks.
