Black Rainbow 

A freshly caught rainbow trout used as a vibrator.

Man, I met this girl who wanted some kinky sex, so I gave her the Black Rainbow.

That prostitute only charged $20 more for letting me give her the Black Rainbow.

black and white rainbow

Rainbow Girl 

A youth organization affiliated with Freemasonry. Though it is not connected to the Gay Community, there's nothing wrong with a Rainbow Girl also being a Lesbian.

Are you a Rainbow Girl?

Why yes I am!

Does that mean you're gay?

Well I am gay, but that has nothing to do with me being a Rainbow Girl. You can be of any race, religion, and even orientation and still be a Rainbow Girl.
