Rainbow Child 

A gay man who would go straight for only one particular girl, but if he can't have her, he will come out of the closet.

Mike: I can't believe Steve is dating Matt! I thought he was engaged to Julia!
Ben: She broke it off.
Mike: Is he bi then?
Ben: No, he's just a rainbow child.

Rainbow Party 

A Rainbow Party is, in all actuality, so that guys can brag to each other how popular they are. The girls wear a different colored lipstick each, suck off the guys they think are hot, until all of the do-able guys have been revealed. Then the guys count how many colors they have, and compare.

Ladies and gentleman of Urban Dictionary, it IS real! I had a good amount of girls in my class, year 2000, come up to ask if I wanted to join. There were pictures all over the school, not in the eyes of teachers, that I got to view and I was quite ashamed! Never even heard of Oprah talking about it, and neither had any of these girls. I assure you, Oprah did not make it up!

John could not believe how many colors he had on his penis! He thought surely he'd only get three at the very least. The sudden boost of confidence he felt was well worth the unease he had had before he joined in on the rainbow party.

Rainbow Room 

A party where a bunch of girls wearing different colored lipsticks get drunk and kiss a guy's penis until it is a rainbow of colors.

Mike: Man, there were so many girls at the rainbow room last night, it'll take me forever to clean my penis.
Bob: I know, right?

Code Rainbow 

Goes hand in hand with the homometer[. When the homometer reaches epic proportions, a Code [Rainbow is announced.

Upon announcing a Code Rainbow, all straight males must cover their asses and run.

"Homometer rising, sir! CODE RAINBOW!! CODE RAINBOW!!!"
