There's so many reasons it rocks. For one thing, it's generically named. This is the sort of thing that would have become a secret society type of thing (like Discordians who laugh at people who don't know what "Fnord" means), yet the point of the game is actively against that. It's to spread to everyone everywhere and conscript them into playing whether they like it or not.
The best way to announce loss of the game, IMHO:
"isn't it true that when the prime minister of the u.k. declares on national television that he has lost the game, the game officially ends?
least, that's the rule where i live."
It's hilariously self referential, gloriously unsecretive, and viciously gripping.
And, by the way, you all lose. 8) Now go forth and make others lose 8)
