Top Definition
A sexual act where a male participant inserts both testicles up the anus of his partner - be the partner male or female.

Allegedly so called because the act resembles the challenge of washing two dogs, at the same time, in the same bath tub.
I was washing the dogs. No sooner had I got one in, and turned around to get the other, the first one popped out so I was back to square one...
