a person with no game console of their own, who constantly goes to his or her friend's houses just to play on there Wii.

I thought Anthony wanted to come over so we could make out; instead he makes a beeline for my Wii and enthusiasticly yells "I will so own you at Wii tennis!" I need to dump that Wii bum.
I'm such a Wii bum, I made a Mii at at least 3 other peoples houses...
Rhonda: I was on my Wii Fit all morning I feel so skinny.
Dave: Oh sweet I'm going to get one.
Rhonda: You can you use mine, I need to go to the buffet anyway to eat something to burn off.
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.
