The act of urinating inside of a man or woman's anus shortly after completion of anal sex. It is so named because a #1 is taken on top of a #2 and the resulting mess is extremely smelly and sticky. As this is one of the most horrible things one human being can do to an other it is almost always accompanied with a subsequent break up.

Yeah, and I gave her the old one two stinkaroo then dumped her.
