Funny name for a wheelchair.

When I was a teenager, "spaz" was the shortened form of "spastic."  We meant
someone who moved clumsily or acted goofy.  If you said someone "spazzed out,"
it meant they lost control of themselves.  As it caught on, one could be
called a "spaz" for just about anything that wasn't "cool."   In retrospect, that
was a rather negative term to use, but teenagers are rather negative beings,
you know?

Anybody know who was in charge of cool? :-)
