during some mad fucking, grabbing your testicles as if you are going to Brain (definition #5) someone then, inserting them into the vagina or asshole. It is very difficult to do, hence the Dog in a bath name.

her pussy looked tight so i thought id try to put the dog in a bath.

Keepin' the Dog in the Bath

The physical act of not only inserting ones testicle into another's anus during sex, but keeping it there for as long as possible. Generally anal sex is conducted before doing this in an effort to essentially "loosen things up." This "move" is performed by perves and shady boombastiqua's alike and is only recommended for such types (see shaddy boombastique). People on steroids with something to prove may actually attempt to insert both testicles simultaniously, although many believe this to be impossible (including myself).
*Note: "This shit is hard."
**Note: Keep in mind that you are on your own. Post-coital conversation following this act may be extremely awkward.

"Last night, I (Jon Yi) kept the dog in the bath for like 10 seconds. That shit hurt so bad but isn't it cool that I can say I did it? Isn't that cool?"

"I kept the dog in the bathtub for a personal record of 5 seconds one time. I wasnt walking the next day though."
