Ass nard
Ass-n-ard: The biological cross between an asshole and a retard.  A person who pisses you off to no end but doesn't know any better because they are so stupid.  This person casues a fit of rage in the person who witnesses the asshole being so damn retarded.
I can't belive that assnard just cut in front of us. If he gets his Big Mac before me I'm going to kick his ass!
