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!
