Douchebags do not know they are douchebags because of their extreme egotistic tendencies. Be warned that an asshole is not synonymous for douchebag. There's the stuck-up , superficial "i am better than everyone" asshole; There's the " i hate the world and everything in it" asshole; there's the "i'm pretending to be nice to your face, but later i'm going to talk all kinds of shit about you" asshole; goodness Sean , the asshole, gave shit to the people around him. An inconsiderate, arrogant, uncaring , selfish, borderline sadistic, apathetic, mean, spiteful, dishonorable , bastard of a man who could tempt the Pope into a fight. They only think they are smart.
