V. Similar to "shart"-ing, having fartarrhea is when a person thinks he or she is passing gas, but a gentle brown mist is expelled from the anus, creating a Jackson Pollock in the underwear. (See Jackson Pollock)

Occurs when a person underestimates their own fart, thinking it is just gas but lets the fart out and diarrhea also sprays out usually making a big mess.
Tracy sat on the couch. She felt a big fart coming. She shrugged and slowly let it out. After she farted, she felt better but she noticed her underwear felt wet and her pants had a big brown stain along with the couch. That's when she realized it and said "damn i had a case of fartarrhea and shit myself"!
