Mexican Rainbow 

Rainwater mixed with oil from several junky mexican owned vehicles leaving a parking lot, creating a rainbow-like effect on the pavement.

José and his homies left a huge Mexican Rainbow in Wal-Mart's parking lot.

mexican rainbow 

When a person eats really shitty Mexican food so that a few hours later he or she - but mostly he, since girls don't poop - simultaneously shits and vomits from both ends. Once the purging begins, the person will get on their hands and knees, and the spewing will look like a rainbow.

Man, last night I went to Vallartas Mexican Restaurant and I had the worst taco and refried beans EVER! When I got home I redecorated my bathroom with a Mexican Rainbow. It was so gross!

end of the rainbow 

In a world where jizz can be multi-colored, a technique where 7 guys all with different colored jizz are jerked off by a midget in a leprechaun suit into the rectum of a pot of gold aka some chick. *If the woman prefers, spraying rainbow colored jizz out of the anus is optional and may be enjoyable for some parties.

7 guys all with different colored jizz step into a room with a leprechaun:
Guy 1: "Hey guys I'm red this time.:
Guy 2: "You were red last time, how about you be green this time?"
Guy 1: How about you fuck a midget. I'm red. You cock jock.
Midget: "Come on guys, lets get wankin'. This chaik is ready for the end of the rainbow."
Guy 4: "Hope she totally sprays that shit all over my balls this time. You know, cause Im into that sort of thing." (*refer to optional rule)
Guy 6: "Come on, you guys are holding up the line. Midget get over here and spank my junk around so I totally jizz in this pot of gold aka this chick who is a total slut."

Dirty Rainbow 

1. The act of puking, pissing, shitting, and cumming all over a person as an act of humiliation, thus creating a disgusting rainbow of different colored substances.

2. When one has so poor of a fashion sense that you can only describe what they're wearing as a "dirty rainbow."

1. I heard Alec gave your mom a dirty rainbow last night when she was passed out.

2. Did you see what Alec wore to the dance last night? He looked like a dirty rainbow!

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!
