a game involving a group of people (usually over three). everyone must get in a circle and on the count of three, must take a random pose. after that, going clockwise, one person at a time must try to slap another person’s hand (any person). if the person hits another person’s hand, the person who was h-t must leave the circle. whether successfully hitting or missing, one must stay in that pose. only the person who’s turn it is and the person who he/she has aimed for may move at a time. the person who is aimed for doesn’t go next; the next person is always to the left of the person who just went. the game ends once only one person is left. this game is usually played to p-ss the time.
