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."

When you try to stuff a set of nuts in a woman's asshole. In turn is as impossible as washing "two dogs in a bath tub".
"This bitch's ass was so loose that I had to give her the two dogs in a bath tub treatment."

It's where a women is in doggy style and 2 men shove the cock in her ass at the same time in a violent matter, leaving pubic hair on her ass and after you jizz in her ass, it will leak out and stick to the hair, looking like a hairy ass, or dogs ass

giving the dog a bath is when a male stuffs the twig and berries in his girls mudbucket and keeps it there as long as possible. if you've ever tried to get a dog in the bathtub, and keep him there, you know exactly why this act is so named.

A dog bath is when you attempt to fit your balls into someone's a-hole. They just won't go in, much like trying to give a dog a bath.
So I was doing this girl and I tried to give her a dog bath.
