A type of erection a paralyzed male gets. It's not fully hard (usually) and will frequently have a spasm causing the erection to bounce up and down.
Girl: (to paralyzed lover) Why's your hard on dancing, does it want it?
Guy: Fuck no, its just a damn chaz spaz.

"Check how fast that Spaz Chaz was going."
