What I got from the post was as the above poster said - that it was being used as an 'off the cuff' response. For example if a person checks if they locked the door more than once they might say "I'm having an OCD moment" and I could see how that would bother someone who has OCD. Or if someone looks sad someone might say "what's wrong are you bipolar or something"? Pardon me for saying those examples.

I'll be interested in hearing from the original poster as to what she meant. It bugs me to no end when people casually use the 'gay' word in an insulting manner.
