'Classic Asperger's' means much the same as 'typical/stereotypical Asperger's'. It's rather like telling someone that they're a 'typical Piscean' etc ... In other words, it's virtually meaningless. The person who told you this has probably watched a few episodes of 'The Big Bang Theory', or read articles in the gutter press, and believes that that makes him/her an expert on autism.
It takes no account of you as a unique person.
Yuk. Find another bar.
