whoopsie-poop 

When a male is standing, urinating, and unintentionally defecates in the process.

So the other day I was standing there taking a piss, when all of a sudden I pooped! What a total whoopsie-poop!

Whoopsie Poopsie 

In Ancient China, this was said (in Chinese translation of course) during anal sex when ones penis came in contact with the receivers bowel movements. After done with the bowel movement, the anal receiver would then spread the poo on a platter and then rub the platter on the anal giver's nipple (preferably left)

I gave this hot asian whore a whoopsie poopsie the other day. She ended up licking it off my titties.
