Basically it's a game where you "ban the person above you" for silly reasons
For example, "I ban the person above me for not existing" (as in, this is the first post of the thread so of course there isn't anyone above this post)
(I hope this will be allowed to stay as a game, not every forum likes this game as apparently it can cause upsets, despite the fact it is literally a game and it normally says "game" in the title of it)
