Volcanic Diarrhea

The combination of explosive diarrhea and bloody diarrhea, and an incredible hot feeling. Given the name Volcanic Diarrhea because when the blood and shit are mixed together it makes for a magma/lava looking substance. Also because the poop is so hot, that it feels like lava is shooting out of your anus. It normally results in heavy crying due to the pain in your rectum, and ends with a long shower.

Some severe cases also contain you calling your loved ones and telling them you might not make it.

Person 1: Hey why did you miss my wedding? You were supposed to be my best man!
Person 2: I had volcanic diarrhea for 6 hours.
Person 1: Oh my god I'm sorry, is there anything I can do to help?
Person 2: Yes, if I ever suggest having Taco Bell again, beat me within an inch of my life.
Person 1: Will do.
