You don't need any equipment to play this game.
The players are standing in a circle. One person begins and calls a name of some other player in the circle. This player now has to duck down, while his two neighbors have to form pistols out of their hands, point those at him and say "Peng" (thus the name). Whoever of the three players is last to fulfill his task gets a negative point (or is the next one to say a name).
