The title says it all but first, there are a few rules. Like almost every other game, the Bulbagarden Forum's rules still apply. There will be no saying that the user is ugly, fat etc. Also, no mentioning weight, anything racist, saying something that someone could take offensively or anything that the member told you not to tell anybody (I.E. A user has down Genderless for their gender because they don't want anybody knowing whether they are female or male but they told you their gender). So in general, keep it nice or you will find this thread closed and possibly with an infraction if you start bashing other members. This is supposed to be fun, not somewhere people go when they want to cry.
An example of an appropriate game:
User A: I think User B has brown straight hair, hazel eyes and wears blue jeans and a sweatshirt often.
User B: I think User A is blue eyed and has blonde hair.
I will start.
I think the user above me is invisible and bald.
