Ah, because I used a translate app and wasn't sure if it did it correctly. So as I found the translation funny, I wasn't sure it was the same thing you were aiming at.
I can't think of anything close. The only thing I got is "rear...something" and "back...something". I don't think it's even a real word in Russian, but it does sound like one, and that's why it's funny (and it also describes ass).
Why the question mark?
