From the mind of Projoy via The Banter Page: "One person sets a conventional hangman problem, but only other players are allowed to reveal the letters or add lines to the scaffold. Other players take guesses in turn as to which letters are in the word. The players who arbitrate over what letters are in the word are not allowed to confer. The shape of the word can only emerge through tacit mutual consent - via, in other words, the collective consciousness." (Winning move is "hanged")
No, no, it's quite clearly a reference to SCATULA, the rockingest jazz-singin' cat on the vampire scene, man. [Collective Consciousness] I take it by your silence that it wasn't SHAMELA, then?
