Shampoosterbate

The act of shampooing your hair while simultaneously master-bating with your other hand.

Last night I only had ten minutes in the shower so I was forced to shampoosterbate to save time.

Shampooing 

To indulge in alcoholic consumption the following day/night after getting completely shitfaced the night before. Usually it's easier to get drunk that next night.

Kate and Lauren are shampooing in the fratmosphere again tonight!

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.
