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.

The Rainbow Defense 

The act of pretending to be homosexual in order to deter the less desirable members of the opposite sex. The move also can inversely serve to infiltrate social circles in an attempt to court a member of the opposite sex, or to deter jealous/suspicious spouses.

The school placed me in Theater (The preferred electives were taken). I used the Rainbow Defense to pull more women in that class. And I was totally gonna end up at one of their sleepovers and 'get curious' until I got expelled from that school...
