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."

parasitism 

A symbiotic relationship in which one species, the parasite, benefits at the expense of the other, the host.

Tapeworms live in the intestines of cats, where they absorb nutrients from the food cats eat.
