The art of forcefully ejecting diarrhea from ones anus onto another person in an arc like a rainbow.

much like the rainbow, the chili rainbow is when there are different rings on a guy's dick from doing many different girls in the ass
I had LaQuisha, ShaNiqua, Belinda and Passion all up the Hershey Highway last night...best chili rainbow ever!

when you insert you cock into a womans ass, then in her vagina (on her period) , once you cum hold the head of your cock, so the cum lays on top of the head...then let her have her home-maid chili-rainbow!
