"There's always one zombie with black gunk coming out of his mouth. See? There he is. What is that black gunk? I don't know! No one knows! It's one of the great mysteries of unlife!"Maybe you're infected by a zombie virus. Perhaps an alien's made a home in your intestines. Or that demon you were trying to summon got a little too close for comfort. Either way, one of the symptoms is Bad Black Barf. Black Barf, as the name implies, takes the form of a thick black goo that issues from the victim's mouth, which they will cough up frequently in varying amounts. Sometimes it may ooze out from the nose, ears, or even the eyes (or some other, less savory orifices). Color might vary slightly, from dark brown to burgundy, but it's mostly black. In some cases the stuff might even be acidic, poisonous, or just smell really bad. Besides the obvious gross-out factor of seeing someone puking, the human body doesn't really produce black-colored fluids, and there are very, very few diseases that cause black discharge of any kind, so combining the two informs the audience that anyone with Bad Black Barf is not just sick, but sick with some unearthly, unholy, or just downright unnatural disease. See also Black Blood.

- The Inky Cap mushroom, so named because it quickly disintegrates into a black ooze shortly after releasing its spores.
- One of the signs of major upper gastrointestinal bleeding is "coffee-ground emesis," so named because blood that has been digested in the stomach looks dark brown-black and granular, just like spent coffee grounds, when it's vomited back up. Yellow fever, viral hemorrhagic fevers such as hantavirus and Ebola, and severe upper gastrointestinal damage from long-term alcohol, drug and/or painkiller abuse can all cause this sort of thing to occur. This association explains why "yellow fever" (named in English for its association with liver failure) is known as vomito negro ("black vomit" in Spanish). Any way you slice it, it's a bad symptom to have; depending on the cause, morbidity and mortality associated with hematemesis runs anywhere from 11-90%.
