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.

Get the shartmug. The accidental discharge of fecal matter, usually of the liquefied kind, when attempting to merely pass gas. If the underwear becomes overly saturated, a stain may appear on the outer garment. This unfortunately results in embarassment and ridicule, if around other people.
