look up any word, like bukkake:
 
1.
Once a year, by invite only, Jim Rome lets his callers insult each other and various sports figures. Sort of the way he insulted Jim Everett by calling him Chris. Except Jim R. got Smacked by Jim E.

You can only be invited if you were stupid enough to sit on hold for 3 hours on one of his previous shows just to insult someone. If you call got racked (accepted) you could be in the smack off. I prefer the Snatch Off. Where Hookers and Clones get together and do the nasty. Fat guys like the snack off. Nothing like cheetos and masterbation. Orange Julius anyone?
Jeff in Richmond won the smack off once. And he sucked. Sean usually wins, because he blows rome before the show.

A degenerate moron who struggles to make intelligent decisions, but inevitably always results in disaster.
That smackoff forgot to tie the pipes to the top of the van resulting in the death of an innocent woman stopped in front of him by impalement.

A real asshole, a jerk, a loser, someone who can't do anything right.
Angus: D'ye ken the wanker by the crapper?

Ian: Aye, 's a right smack-off, ain't he?
