Even more whorish than a dirty 1:30, a girl you pick up outside the bar after it closes usually around 2:30 am that you don't have to impress at all. She could care less who you are, she just really wants to get banged.
Dave: Did you end up picking up that girl at the bar?

Me: Nah, but I picked up this dirty 2:30 instead.
