Hug A Rainbow 

To embrace people of all shades, colors, nationalities, etc.

To love the human race

Bob: Sally is so cool she doesn't discriminate at all, she loves everybody.

Sandra: That is true she's always hugging rainbows.

Stop being a prejudice and go hug a rainbow!

double rainbow

A rare type of rainbow that may appear all the way across the sky after a period of rainfall. It can be described as very bright, vivid, and intense. However, many have fallen under the belief that a double rainbow is slowly transforming into a triple rainbow. This is impossible, and is an illusion created by either intense sunlight or a rainbow forming adjacent to the double rainbow.

Double rainbow, oh my god! It's starting to look like a triple rainbow!

Chillie Rainbow 

The act of performing anal sex then performing normal sex while the woman is menstrating then take the residue and fecal mater and spread it over her stomach in the form of a rainbow. Thus creating the chillie rainbow

"Grisel had her period so I had to fuck her in the ass, then I fucked her in her vagina anyway and gave that bitch a chillie rainbow."

Roast Beef Rainbow 

(n.) When a female, standing on the ground, urinates upwards in an arc onto an elevated bed or other high place. A specialized form of the Golden Shower, this feat is more difficult for women than peeing standing up, even into a urinal.

"Can she use a urinal? Man, yesterday I seen her hit the ceiling with a roast beef rainbow!"

Double Rainbow

When a girl gives a guy two orgasms in a row. The second one is usually more intense and as rare as seeing a double rainbow. Triple rainbows follow similar logic but are almost impossible to achieve in heterosexual, mature men.

Last night, Leona gave me a double rainbow with back to back blowjobs...Best sex ever!!!
