A game which requires slapping the under part of someones arm. You are allowed to slap the arm only when the arm is exposed. You cannot pull the persons arm up against there force. If they aren't paying attention you can lift the arm up but you can't lift it against their will. You can chose to get them as hard or soft as you want. You must yell the words "Jiggle Pit" or you don't receive any credit for the strike.
Guy: Hey, billy's underarm is up I'm gonna Jiggle Pit him.
*slaps underarm*
Guy: JIGGLE PIT
