It's possible to poop out of your mouth
It's called fecal vomiting, and aside from being utterly disgusting and terrifying, it's an indicator of a major health problem. Though if you're vomiting your own poop, you probably know you have a major health problem. When people have a blockage in their small or large intestine, known as an intestinal obstruction, waste can't travel to the rectum.
"If you have an obstruction generally in the lower small intestine or within the colon, you can eat food but it has nowhere to go," says Dr. Ben Dalton, gastroenterologist at the University of Tennessee Medical Center. "Eventually, you hit a critical mass and if it cannot get out from the south, it'll come out the north." That means you will vomit fecal matter; it probably won't look like regular poop, but it's as disgusting as it sounds.
Fecal vomiting is usually accompanied by abdominal pain, dehydration, and constipation, and untreated blockages could lead to death. Fortunately, Dr. Dalton says this is pretty rare.
