Short for 'Vampire: the Masquerade'
One of those stupid things we geeks play to waste time. A type of RP/RPG. Be careful while playing this game, as some of the people can be quite deluded and think that they aren't just PLAYING as vampires but actually ARE vampires.

An acronym for "Vampire: The Masquerade", a tabletop RPG written and published by the staff of the RPG company White Wolf. One of their most popular and (in)famous games, it was discontinued recently (as of this writing). The "heir to the throne" is "Vampire: The Requiem", a similarly structured game with a different backstory and rule system.
Vampire is one of several tabletop RPGs that comprise White Wolf's "World of Darkness" games, and has a not wholly undeserved reputation of attracting goths and the disenfranchised.
