How do you reject a guy that is freakishly hot but stuck up?

It seems very shallow to be classing someone as 'hot' if he had bad behaviour. Maybe I'm old-fashioned but I would say a person's character and behaviour dictate their overall attractiveness. It's part of who they are, just like the chin stubble or the gorgeous brown eyes. After all, a tiger looks great but you wouldn't want to date a hungry one.

Tell him your parents grounded you and you can't date right now...or just tell him your not interested.
