I've heard Townie stateside pretty much used interchangeably with Hippy. For example, a pothead with long dirty hair and psychadelic clothing might be called a townie. It is generally used as a term of derision.

I've only heard the term a few times, so correct me if I'm wrong. I don't think I've heard the rest of those (with the exception of wigger and goth).
