Step-Bag

A person's step dad who in all means is a douche bag that thinks he knows what's right all the time, usually get's the last word on things, labels his sons friends, and does ass whole-ish things.

That thing your mother marries when your real father is no where to be found. At first he seems okay, he buys your family stuff and is seemingly nice. Then after a couple of months of marrige to your mother he becomes more assholish, then him and your mother are fighting, and what does the asshole do? He punches your mother in the fuckin face! He is the anti-christ. Don't be suprised if you want to kill him or throw something at the sumer toothed son of a bitch!
