I first heard the term from the claymation film 'Mary & Max'. I think it's like a nickname that people call you when they call for you. For me I think it's like being called 'Ginger' but when it comes down to it it's a matter of opinion. It's all about whether you're offended of not by being casually referred to as 'Aspie' and whether people call you it to be offensive or just as a nickname. If I was diagnosed with Aspergers I would refer to myself as an Aspie as it would just be a short term for a condition. It's all up to you really, so just call yourself what you like
