This happens when you over-play the Nintendo Wii.

Your arm begins to ache, and somewhat burn slightly... Using your arm for any kind of quick movements, or outstretching of the arm generates pain.
You get Wii-arm by playing WiiSports for 14 hours non-stop - Then trying to play Baseball, and finding out that you hit the floor in pain when you swing.
