Errhead

Bridging the gap between "Errol" and "airhead", this insult applies only to those named Errol but deserve to be condemned for the losers they are, hence they are an "errhead"

Errol can't get over himself and constantly annoys people. Why he's such an errhead! Hey, that sounds like "airhead"...oh wait, that's precisely what I called him. I'll call that hated bully Errol "errhead" if he picks on me again.
