(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.
Sorry, I won't be in to work today, I have a bad case of fiarrhea, in fact, I may need a colon transplant.
Excrement from the anus usually caused by the digestion of spicy foods. The fecal matter is characterized by a diarrhea-like consistency and results in a burning sensation of varying degree on or around the anus. Particularly unpleasant when mixed with a hangover.
I got the fiarrhea from that spicy shit I ate after going to the bar last night
