cambodian rainbow 

This is a sex position where the man is having sex with a woman suffering from a cold or flu, or other stomach problems. Shortly before the man ejaculates, he pulls out so the female can vomit on his dick.

My girl hasn't been feeling well all week, but I was really horny anyway. She ended up giving me a cambodian rainbow.

the double rainbow 

A gay sex position where a man does a back bend, then the second man inserts the first man's penis into his rectum, then proceeds to do a back bend over the first man with the penis still inside of him.

He's so gay he did the double rainbow with your dad last night!

taste the rainbow

A girl paints a guys penis the different colors of the rainbow.

A group of girls and a group of guys get together. The girls paint the guys penis's the different colors of the rainbow and then the girl that can swallow the most colors or "taste the rainbow" wins.

Double Rainbow

When a male jacks off two other males, especially if they have big dicks.

Last night, I saw a double rainbow!
Dude, you weren't part of it?
Nah, I sat back and just enjoyed it.

taste the rainbow

a line of women get on their knees, and each put a different colored skittle on their tounges. Then a man 'whips out his shit' and mastribates on their extended tounges. When seaman is librally spread over the faces of the women it will turn colors due to the skittles. The mentioned women then close their mouths and enjoy! :)

Yo! Dave let Jenny, Heather, and Stephanie 'taste the rainbow'!

irish rainbow kiss

performing oral on your female partner while she is having "that time of the month", then proceeding to make out with her.

some may find the irish rainbow kiss disguisting, but I find it has a rather tangy taste to it.

Over the Rainbow 

When you are about to orgasm during doggystyle pull out and shoot your love load straight over your victims head causing her to not only see your man seed but also leave a pressure losing line of salty boogers from the front of her hair line straight down to her ass crack.

I was doing this chick from the back when I launched a mean over the rainbow that fucked up her hair hardcore........ then I kicked her in the crotch.
