Too much 'PC' for anyones good...
To a degree I concur with Brian Miller's comments... That is, growing up, I always used "spaz" or "spastic" as a term to describe being/going crazy - before I ever knew ANYTHING about Parkinson's, or any other 'illness'...
For example; "When I have an energy drink, I can go quite spastic."
Guess what? I STILL USE IT IN SAID CONTEXT - the above statement is not very rare to come out of my mouth when I've had caffeine....or to describe my cat.
It fit the rhyming scheme, and this is (more than bloody likely) the intent of the word - to go crazy. There's a time and place for various verbages - I'm not necessarily going to use this term around anyone who has an "illness" (heaven forbid that I say something right now to offend anyone). This reminds me of the South Park Christmas episode where they school goes to put on the Christmas play, it turns into an "artsy-techno-new-age-light-show" - wtf does that have to do with Christmas?? Too many people where offended by this and that.... Jewish people offended by this... Christian's offended by that.... etc.. etc.. Where does it all end?
Simply put...if a term (or something) is used in a derogatory way, it's wrong. If it's not, well, it's not. As far as the 'gay = crap' comment(s).... that's simply something I will always find derogatory (or simply not right). Why? Look at the translation: 'Gay = Crap' ... "Happy = Crap" ... or "Homosexuals = Crap" ... to describe someone who is very happy or homosexual as gay, well, that's how the bumble bounces I guess. I could go on and on about this because I know so many people (personally) that JUST DON'T FRICKIN' GET IT! lol argh...k, i'm done...for now....
