This is a proper name for when you attempt to insert your nuts into a girl's ass. It is so named because it can be just as hard as keeping a dog in the tub while giving it a bath.

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".

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
Dude, me and jon put two dogs in the bath tub at jenny's house last night and she was screaming until we jizzed in her ass and she calmed down!
