This is the given name to a certain position in which someone playing WoW (World Of Warcraft) will typically sit over the long preiods of time they play wow. The position is adopted by so many as it gives a much more comfortable feel to your position over long periods of time, and to make easier access to use of the keyboard. It has been known for books to be placed on the desk next to the keyboard to rest the arm in a certain position as part of this position.
For the best example(s) of the WOW slouch, I can think of off the top of my head watch the episode of South Park 'Make Love Not Warcraft'. or alternatively ask the biggest no lifer you know who spends their life on WoW to show you.
