Okay, take this tounge in cheek as I was "stuck" in a wheelchair for a summer during high school (amazing football injury, ask me about it if you are really interested) and this is some of the terminology I used.

Non wheelchair bound people walk, the person in the wheelchair gets to where they need to go!

The person in the wheelchair is a gimp (I was in a hip to toe cast, and that was the nickname I earned.)

Act of controlling? scoring points hitting pedestrians (which was easy to do with that foot stuck way out there!)

I like silly, it makes the universe less serious!
