Part of game of 'slaps'. Called by the slapper in a game of slaps to refer to the fact that although the slapee moved his hands out of the way, the slapper's finger-tips caught the victim's hands, thereby entitling the slapper to another shot. (Question: who played the 'free slap' rule, where if the slappee flinched 3 times when the slapper was bluffing, you got a free slap?)
