Situation where one vomits from the mouth and excretes human waste from the anus at the same time. Can be caused from laughing, ridiculous weirdness or excess consumption of alcohol.
This is the Mother of all sharts. When you try to simply fart and power spray liquid shit which soaks through your underwear and runs down the back of your legs.
We all had to take a pay cut to keep our jobs. Then we found out the asshole paid his son in law a 9K bonus for being a summer intern. I ate a whole jar of jalapenos and sprayed his front door with a Mexican Shart! You can still see the stains from the runny shit!!
When you fart so propulsively, you believe a trace of shit particles escaped into your trousers. The ensuing five minutes of mental deliberation of whether you have any fecal matter in your pants is like a five yard false start penalty for an offense in football.
After eating shrimp at the Chinese buffet, I farted outside the restaurant. I wasn't sure if I crapped my pants, and it took me a while before I realized I just called a false shart penalty on myself.
