When you have to shit really badly and you let out a fart thinking that you'll be ok, but really shit comes out with the fart.
Resulting in ruined underwear and possibly in need of a new pair of pants.

1: Commonly and more particularly, an unforeseen form of defecation occurring only when one has solely anticipated and partially succeeds in the breaking of wind.
2: An unintentional defecation that occurs when attempting to break wind.
3: The accidental emergence of excrement during the release of rectal gas.

Shart:

Etymology –
English: First notably expressed within the later part of the 20th century as a slang mixture and more typically used in the United States. The word is used in the movie “Along Came Poly”, but, the words exact origin and period of conception is not known. Shart is the unification of the first two letters from the word “shit” followed by the last three letters of the word “fart”; Sh ~ art.

Cause –
Typically a shart is induced by diarrhea that has not yet displayed its symptoms and the sufferer simply feels the urge to pass gas.

Remedy –
Self regulation:
When the urge to pass gas initially begins, the sufferer should attempt to restrain from allowing release for a few minutes. Typically a shart can be avoided as the symptoms of diarrhea will be sensed a few minutes after an initial false gas episode has occurred.
Medical:
If this a common occurrence one should consult with a physician.

The act of forcing a fart out of the anal region of the human body and accidentally losing control of bowels. Once this occurs, a feeling of utter disgust will be inflicted on said person who committed this act. There are many options on how to deal with this situation. A common solution for many people is to immediately find a lavatory or restroom facility of some sort. Check the underwear for any fairly large pieces of fecal matter. Remove said fecal matter and wipe your buttocks and any other affected areas clean with toilet paper provided. Forcing out a fart is very risky. It is not recommended to do at social gatherings.
Even though Winchester can fart on command, he sharted after eating a White Castle Crave Case.

Molly could not take the pressure of keeping in a fart, so she blew one and ended up sharting.

Bradley knew a fart was building up inside of him. With an atmosphere full of humor, he could not resist breaking wind. He did not know that his rectum was full of feces. Without hesitating, he let one out and suddenly a wet floppy sound came from him. At that moment, everyone stopped laughing and were disgusted. Bradley just sharted. He risked getting his pants dirty. He risked losing his dignity.
