look up any word, like fuck boy:
 
1.
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.
dude 1: yo dude, your dad was grillen the shit outta me

dude 2: that's my step-bag for ya.
