A computer-roleplaying-game player, whose character is such a high level that the playing is actually getting a bit boring. It can either mean a player who moves very slowly in the game, preferring to level up than follow the plot; a player who is stuck in the plot and wanders aimlessly trying to find a way to continue; or a player who has almost completed the plot, but doesn't want to game to end and is just wandering, unwilling to finish.
The term originates from the Douglas Adams's novel "
Life, the Universe, and Everything", where an immortal grey-
green alien by the
name of Wowbagger the Infinitely Prolonged travels the universe in order to insult everybody in alphabetical order. Also, WoW stands for
World of Warcraft, a large, popular multi-player online roleplaying game.
