Shartnart 

Shartnart is when you shart yo stanky pantaloons in the freezer and it piles up in your pants a bit too much that it reaches the top of your head like a tower and now you have a cozy hat that protects you, a cute name to describe this event would be shartnart

“Man bud, that shartnart looks unbelievable, what did you have for dinner?”

rapid shartation 

Starts out as passing a little gas or silent trouser sneeze and quickly develops into mass poop flow from the anus area, usually wet and very unpredictable....

After eating the wet Sancho at Taco Casita, I experienced rapid shartation in the car on the way home.

Shartnado

An explosive unintended defecation that occurs when one relaxes the anal sphincter to fart, with a twist.

After my fifth bean burrito, and three cups of coffee, my bunghole released an EF5 Shartnado that leveled my pants.

To shit, fart and urinate all at the same time.

1. Joslyn was laughing so hard that she shartinated and had to excuse herself to change her drawers and recover her dignity.
