(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.
