Playing Wii or a Wii game so much that you go into almost a relapse state from being away from it. Usually caused by playing the game on a friends console, or one that you don't have accessible. Symptoms include raving on about the game you were playing and trying to convince people to get it. Or trying to convince your parents or yourself to spend the money and buy it.
