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!
The epitome of all asses; a derogatoy word (noun) typically utilized in defiling a particular species of homosapien expressing excessive abnormal behavior.
Hey assbag, get the hell off of the road!
Your mother sucks assbags in hell!
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".
