sphinctermeter

The part of the anus that manages the delicate flow of waste which differentiates and carefully selects what shall pass based on it's current state - whether it be in solid, liquid or gas form. This phenomenal muscle is highly used when diarrhea is present and the person is unsure if there is a liquid or gas eager to exit from the anus. In many instances it allows gas to expel while delicately holding back a tsunami of molten fecal matter. During moments of constipation however it remains unused.

Josh: Dude the other day I was at the movies and I had some major diarrhea. Luckily my sphinctermeter let me release gas from my bowels while keeping back the mother load of explosive goo.

William: Dude that's disgusting. Did you eat something bad?

Josh: Your wife's chili.
