A Nat Rat is a nocturnal creature. Choosing to stalk its prey at night, the nat rat jumps between bars and parties seeking out unsuspecting individuals to seduce. She is rarely seen without her "rat pack", a motely crew of long-term drug abusers, alcohols and future college dropouts. Wop parties serve as watering holes for local nat rats and recruitment centers for future rat pack members.
Have you seen the nat rat?

Yea, the last time I saw her, she was blackout drunk and blowing four black guys at the local goodwill.

Didn't you last see her at lunch on tuesday?

Yes.
