shampoot 

The act of farting in the shower. It is usually done without thinking first. For some reason only the gods know, these farts smell a billion times worse than normal gas passing.

I was rinsing, lathering, and repeating before I let out the mother of shampoots.

Shampoop 

When you take a bottle of shampoo and stick it in your ass, squeeze as much of it into your rectum then blow it all over some bitches hair. Resulting in a mixture of shit, shampoo, and hair.

So you wanna come over and I'll give you a good ole fashioned Shampoop.
