brown rainbow 

A term used to describe the effect on a man's penis when having doggy style intercourse with a woman who wipes from back to front, thus leaving a small amount of feces around the entrance to her vagina.

My friend was fucking Misty from behind, and after he pulled out he noticed he had brown rainbow. Misty is a dirty ho.
