Muff

When someone says or does something stupid you apply the MUFF. Can also be applied via a braced MUFF. Taking your index finger and middle finger putting them together and applying pressure behind the idiots ear(just along the hair line) and pulling/swiping towards yourself catching they're ear. And hopefully achieving a snap noise and a disgruntled look of confusion from the receiver of the MUFF.

Guy: I think Larry the Cable guy is fricken hilarious...
Friend of Guy: Holy shit dude. I think you got a MUFF comin...
Guy: What? He's really funny.

Friend of Guy: Applies his index and middle fingers behind Guy's ear and swipes that shit... Achieving a loud snap sound.

(Guy then realizes he was being an idiot and apologizes for saying Larry the Cable Guy is hilarious.)
