The condition tha occurs when eating something so damned spicy that it burns the anal tract. "Spicy in, spicy out". Also these symptoms will arise when eating bad food or ingesting items that have been in the refrigerator for way too long (i.e., leftovers from a restaurant that is now out of business).

Diarrhea. Not just your average diarrhea either. This is the kind that explodes out of your ass and leaves your butthole chapped for the next few days. It is a hot, burning diarrhea that smells worse than vomit. This is as bad as it gets.
I ate at Denny's tonight. I think I am going to have the worst butt lava tomorrow. I better take some imdodium.
