This is a game best kept for tzevet kef, but can be attempted with the hanachim. Everyone sits in a circle, and has to name something that will beat the previous suggestion. For example, and this is an unusually clean example, pirates will beat ninjas, but fire will beat the pirates by burning their ships, but water beats fire and Ribena beats water. The game continues until people get bored, which if done in a proper obscene manner, will be about an hour later.
