The term 'Cockass' refers to a faggot, or just some idiot who has pissed you off. Calling someone a 'Cockass' is another way of calling them a faggot, in comparison to a fag recieving a cock in his ass.
Also,
never use this term around a
gay, or you WILL regret it. Unless you
love being man handled and have a throbbing cock in your ass.
