I think Shiz Kids (or, I've seen spelled shiz kidz) is so much better.
FOR DRACULA - the fan site (from which I gained my name bso) was called the order (of Dracula).
I've heard Mizzie for Les Mis - and consider myself a mizzie.

And back when I coined the term (sort of) enLIGHTest for Piazza fans. That seems to have cough on - at least korenglish uses it!
I think CARRIE fans should be known as the Bloods.
