Brumsmack 

A game intended for two people where the players smack their hands. One player goes first, and smacks the other player's hand, first softly, and then increasingly harder. The loser is the person who quits the game first because they are in so much agony. A modern variation on Mercy.

Jeffrey: Hey, Danny, I'm Bored.
