When a man tucks his penis and balls in between his legs so it is pointing out of the back (similar to the "goat" or silence of the lambs tucking), you then back up to a urinal, bow forward and piss out the back.
I was so drunk at the game last night that I decided to drop my pants to my ankles, turn around and do some back pissing in in the urinal.

Get the push backmug. When two sexual partners engage in doggy style in a walk in freezer. When the man is about to ejaculate he pulls out and discharges over the female's back and rubs it in. This will cause the woman to exclaim 'ooo, ooo' like a gorilla due to the extreme sudden heating of the woman's back during said ejaculation. For added realism the man may beat his chest at the point of orgasm,remove pubic hairs and sprinkle on semen or make an African American individual the sexual partner.
