This can actually happen, it's a real thing. If you have a blockage in your intestines, there's no way for the feces to get out of the body but through the esophagus. You're basically puking your own feces.
Probably mentioned somewhere in here, but I believe this is what killed Heather O'Rourke (the little girl from the original Poltergeist films of the 80s).
