noun. Not a rat fink, a rat bastard, a sewer rat, or a rat terrier. Nope, this is a rat with fame, and a purse-dog, and an entourage (don't call it a pack). This is a celebu-rodent of the first order.
Real citation: "That darn Bug...she's the first Celebu-rat, i know...."

Made-up citation: "Would you feel better about the vermin scurrying across your torso if you knew they were celebu-rats? Most Americans would. In fact, 9 out of 10 people say they'd never wash their torso again."
