Example: I tried the cat in the bathtub last night. What is that? I tried to put my balls in my wife's ass. How was that? You every try putting a cat in the bathtub?

Ok first off, I've seen this as dog in the bathtub on this site and it is wrong. Dogs love water, cats hate water. Which is why when you are fucking a girl in the ass and manage to get your nuts up in her too it is called cat in the bathtub. Have you ever tried to keep a cat in a bathtub? It is about as tough as getting both nuts up a girls ass.
I was fucking me Julie in the ass last night and I stuffed my nuts in her ass too. Man, she thrashed around like a cat in a bathtub!

The sexual act of placing both penis and full scrotum inside the anus of your partner. Said act is aptly titled as pertaining to the complication factor of performing the act of keeping a Dog in a bathtub.

A reference to a scrotum that is very loose and elastic-like. Could occur in warm bath water or any other situation in which your privates are very warm and stationary.
