smack upside the head

To extend your arm so that your hand is below the back of a person's head and thrust your hand upwards so that your palm hits them square in the back of the head.

This is typically done when someone does something stupid or just to humiliate/annoy them.

When Rose started to take diet pills, her mother gave her a smack upside the head to knock some sense into her.

As John sat in the passenger seat, the driver acted like her was streching, but really smacked John upside the head and hillarity ensued.

Smack Off

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.
