I think "spaz" disconnected in enough people's minds from an actual physical condition that it probably isn't meant offensively in most situations, but that doesn't mean it shouldn't be avoided.

Off-topic discussion. Wanna talk about corsets, duct tape, or physics? This is the place. Detailed discussion of any current-season TV must be whitefonted.
In a way, it's equally as offensive as "'sode" which also isn't all that funny when you stop to think about it.
I only found out the "spaz" thing recently.
This Gray's Anatomy is Bananas! Like, insane!
I need to get that out of my vocabulary, at least in the way I used it above. I didn't mean it offensively.
It was a THREE HOUR LINE. And we are in theory doing this again for a different camp next weekend. What the fuck.
I can't stop laughing at this Grey's Anatomy!
In London, when we said spastic, we meant CP. So there was no divorce there. When you said someone was acting spazzy, you meant they were acting like they had cerebral palsy, no distance at all. It's a hard jump to make.
Up until recently with all the fail discussion everywhere, I would never have associated those things.
I think most people haven't encountered people with CP. I personally haven't met anyone with CP that has jerky/twitchy features, so I wouldn't even associate spastic with it.
IIRC, use of the word "spaz" was the source of one of the ugly kerfluffles in Bureaucracy. (Some dude who I disremember -- obv. not a current poster -- said that because this is a board about BTVS, and because the show used the word, that should be our touchstone, and therefore it was okay to use it. I posited that it was a damned good thing this wasn't a Huckleberry Finn board.)
