No I'm guessing its like one of those word of mouth things that once you are told what it is, you are a "member" and can derive fun from people not being able to resist finding out from you what it means and so on and so on.
We had a game at our school called "The Game." The object of the game is to forget that you are playing the game. As soon as you remember you are playing you lose, until you forget again that is. Once you've heard about it you are technically automatically playing it and if you never recall it ever again I guess you win.
Still now I get texts from my friends reminding me that I have lost the game.
I'm guessing that ignorance really is bliss!
