A couple of friends and I were trying to think of a way to properly describe a guy who was such a jerk. We couldn't decide if he was an asshole or a douchebag. Thus became, Assbag!
He is being such an Assbag!

Assbag
The epitome of all asses; a derogatoy word (noun) typically utilized in defiling a particular species of homosapien expressing excessive abnormal behavior.
A device not unlike an airbag that would lessen the injury suffered by an individual who has just been knocked on his ass. First usage found in a skit on Styles P "A Gangster and a Gentleman".
Your ex-bf who is such an amazing asshole that he cheated on you for four months, lied straight to your face twice when you asked him about it and then thought that since you knew about it you could keep seeing each other while he kept dating the other girl without telling her about you because he didn't want to hurt her.
