I have been called "ret*d" for doing various things because of the incorrect way people use the word. "OMG, that's like so effing ret*d/gay/stupid/weird/crazy/etc." I think I have been called ret*d for making "normal" mistakes or disliking certain genres of music, certain films someone else liked, or things like that more than I have been for doing anything that is an obvious result of AS or that remotely looks like something stemming from some kind of mental retardation.
I do not make unusual noises or movements often, so when I do, people are usually too freaked out/puzzled to think or say I am ret*d or anything of the like.
