Dirty Rainbow 

When you shit across the bottom of someone's windshield, so that when they turn on their windshield wipers, a glorious rainbow of shit is painted behind the wipers.

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!

Dirty Rainbow 

The act of sticking you whole hand up someones asshole, then pulling it out and smearing it on them, openhanded, in a semi-circle pattern to resemble a rainbow. Similar to a dirty sanchez, but this is much bigger and can be done on other parts of the body.

Hey man, I just gave your sister a dirty rainbow.... Then I shot her my pot of gold.
