dilltoid 

Dilltoid. Noun. A person who is a general douchebag, and mainly annoying in their actions.

You are at a bar waiting to order a drink. A dude walks in and cuts directly in front of you and orders a drink, and may possibly even say something to the effect of "sorry bro, didn't know you were waiting, my bad" and continue to order a beer. You turn to your buddy and say "what a freaking dilltoid".
