When World of Warcraft players (aka: nerds, geeks, wowheads, etc.) vanish from school and social circles after a new expansion of WoW is released, as if they are hibernating.
Ken: Hey man, where the heck is Danny? I haven't seen him since last week.
Michael: Dude... Cataclysm just got released, he's totally wowbernating.
When a professional WoW player has developed a beard while not moving away from the computer. Some WoW players develop this beard over long periods of time, allowing them to store Keyboards, Mice, Monitors and even extreme cases of replacement computers within these beards, in case of breakdowns. The same term may also apply to CoD beard or Runescape beard.
Oh no, I justbroke my mouse. 'pulls one from WoWbeard'. All good, ready to play
