A classy lady caught in the act of washing her vagina in a mud puddle between clients while hooking. Often the "puddlewasher" is homeless, strung-out and wearing a skirt.
Brandon - Dude! Did you just see that?!
Dennis - See what?
Brandon - I think that hooker was just washing her vag in a mud puddle!
Dennis - A puddlewasher?
Brandon - That's fucked up. Let's get some lunch. I'm starving.
