Paris-itis
Parisitis or Paris-itis is the unfortunate series of circumstances during which an adolescent (usually female) becomes exposed to and contracts the Paris virus (I don't mean syphilis) and begins to emmulate a certain spoiled Hilton family member. The individual is then refered to as a Paris-ite or, more commonly, a Parasite.
"Hey Benson, did you see that girl in the Prada sunglasses yelling at the waiter?" "Sure did Lushman, looks like someones contracted Paris-itis."
