That wikipedia entey covered it quite well. Doesn't sound offensive to me.
Anyway, the example story from the bathroom was very sweet. I reallyliked what Indigo pointed out.

My son is very obviously physically clumsy (sensory seeking) and people are always worried that he is hurting himself. He also was diagnosed with asd, and is truly socially inept sometimes. :P I have to explain alot of social stuff to him. Helikes people... he just has weird ways of showing it. Often people feel put off by him unfortunately. Even people that he likes and wants to keep around. He's still young though! I figure that I have years to teach him this stuff. I hope!
