One of many Mind-Fuck Games, notoriously known simply as "The Game". It instills fear by mere mention. You need a few people who know the rules, and at least one who doesn't. This translates into "pick a bunch of people to mind-fuck someone else".

The object of The Game is to figure out how to play. That's it. That's all you have to do. Easy. Oh, and everyone who does know how to play fucks with you so it takes you as long as possible. Here's what the poor sap who doesn't know how to play observes: One player names three objects, words, phrases, whatever. The other players that know that game figure out which of the people playing these three objects or whatever has to do with. In other words, correlate that group of three whatevers with a person present. What the poor sap doesn't know is how. And the other players name him some groups of objects - maybe three things that a particular person is wearing - to steer him along one line of thinking, and then it ends up correlating to someone totally different.

So what's the catch, right? It's simple. As soon as the third object/whatever is said, the next person who speaks is "it". The objects themselves have nothing to do with it - it is in fact not decided until after they have been spoken.

Example. Bob and Luke decide to play The Game with unsuspecting former friend, Freddy. After explaining to Freddy that his goal is to figure out how to play, this ensues:

Bob: babies, hotdogs, and 9-irons.

Freddy: What...how should I know?

Luke: Well, you should know, it was you!

Freddy: Hmm...

Luke: OK, I got one. Red shirt, blue jeans, white socks. (obviously describing Bob's outfit.)

Luke: What do you think?

Freddy: Is it Bob? It must be Bob.

Bob: Nope - It was Luke this time.

Bob: OK, one more. Babies, hotdogs, and 9-irons.

Luke: Well I should think you know this one...

Freddy: Ooooh, its me, its me!

Bob: Sorry - I'm afraid it was Luke.

Have fun with it, and for goodness sake make the poor sap work for it!
