On past forums i have been on, this game has existed.

Its called the Your Banned Game

Basicaly the person that posts after me has to give a reason to ban me.
For example they can say:
Divine is banned for sucking his sisters titty

then the next person would give a reason to ban that guy
ex) blahblah is banned for drinking horse semin ehile eating monkey turds.

Just something fun that i have seen on this other site.

You're banned for making a stupid, yet truthful thread title.

Your banned for confusing me...
