Similar to tennis elbow, wii elbow is pain in one's arm (particularly around the elbow) caused by too much wii tennis (or, possibly, not enough regular exercise).
I got a horrible case of wii elbow from all that wii tennis yesterday.

The pain experienced from playing any wii game (mostly wii sports) for extended periods of time. This mostly deals with wii games that require lots of arm movement.
