(n.) Extremely painful condition that occurs after eating any variety of extremely hot food such as habanero peppers. Fiarrhea causes a violent expulsion of the spicy material with very little digestion, resulting a fiery hell in the anus. The output is very gaseous and acidic, which more noxious than what was eaten. The victim of fiarrhea must spend many painful loathing hours on the toilet, regretting that culprit bowl of extra-hot dose of demon salsa.

An agonizing type of Diarrhea that fiendishly licks and tickles the pain receptors of your anus. Most commonly the result of ingesting excessive amounts of spicy foods. Fiarrhea is at least kind enough to fire a round of warning shots, although these are probably the worst part of all. Scalding hot and rapid farts scrape and crawl out of your crack, leaving a massacre of singed ass hairs in their wake. The burning sensation clings to your nether regions long after the shit storm has passed. Wiping only intensifies the burning.
