Always a male. An ex-boyfriend you wish you could get rid of by squashing, like the little cock roach he is. An arrogant prick that claims to break up with you but continues to stalk your facebook page. He makes idiotic comments on your facebookhappiness status updates, hoping to kill your buzz, but the fact that he is still watching you only makes you realize how pathetic and small he really is. His sarcasm is much to be desired and completely shows his lack of intelligence.

Lilly: "Oh well, Tyler broke up with Kris, but continues to comment on her facebookpage with stupid comments"
JJ: "That right there would be a prime example of dooshbagery"
