I used to play WOW - World of Warcraft (a MMORPG, or massively multi-player online role-playing game), but I stopped when I realized it was eating up way too much of my time. (That time I now reserve for shows such as Big Bang Theory and True Blood.) Because of my WOW days (and before that, Anarchy Online), I now have an extensive vocabulary of gamer-speak that is unique to MMORPGs.
