A form of stomach upset that you get from drinking too many unfiltered craft beers. Symptoms include feeling bloated, diarrhea, watery stools and a general feeling of malaise. Expect to have intense diarrhea which makes your rectum bleed from excessive wiping for a period of about 12 hours after the last beer is consumed.

Karen and I went to that new micro brewery in town and although the beer was good, I have the worst grain belly from it.
