Facing a partner, players slap their legs and say "boom," then point in a direction (either up, down, left, or right) and say, "chhh." This pattern repeats until both players point in the same direction. At that point, they slap their legs on the next "boom," then point at each other and say "woo!" The players return to the boom-chhh pattern until they point in the same direction, which is again followed by a boom-woo sequence.
