Rhode Island Rainbow 

The act of receiving a Diet Coke enema and carefully inserting Mentos into the anus right after the sugary butt chug. It is very important the participant bends over to produce an arch (or rainbow) of shit/Diet Coke as the fountain of carbonation rockets out of their anus.

The stripper at the gentleman's club did a Rhode Island Rainbow during her routine. It was so hot.

Bristol Rainbow 

It’s when you analyze your shit from A to Z and you realize that it contains different matter states with all the different Bristol stool chart numbers. There should be 7 different states of fecal matter in the toilet, going from liquid and watery to very solid and concentrated.

Usually, what happens is that you ate in a Chinese Buffet the day before you take the dump. There are so many varieties of food in these places that your body sorts them in terms of solidness, going from the egg roll sauce to the chinese onion rings’ crust.

If this ever happens to you, go see a doctor immediately. The Bristol Rainbow a very rare case, but when it’s there, it stays for a long time.

Rod : Doctor, about the sample of crap you asked me to give you last week...
Doctor O’Brien : Yes?
Rod : Well, which part do you want the most? There’s the liquid part, the soft part, the solid p...
Doctor O’Brien : Oh my God... Rod, you did a Bristol Rainbow ! Congratulations!
Rod : So, this is a good thing?
Doctor O’Brien : Actually, I was being sarcastic. Be prepared to pay the price for your prescription...
