Dark Matter Diarrhea (DMD) is an elusive, yet universally acknowledged, gastrointestinal phenomenon characterized by the rapid and often explosive expulsion of non-baryonic matter from the digestive tract. Unlike its baryonic counterpart, DMD is invisible to the naked eye but can be "felt" through its subtle yet catastrophic effects on local spacetime, often resulting in minor gravitational lensing, the sudden disappearance of small household pets, and an inexplicable craving for tuna casserole. It's believed to be the universe's primary method for expelling excess dark energy or poorly digested Quantum Custard. While generally harmless to the individual experiencing it (beyond the inherent social embarrassment of a localized spacetime ripple), the environmental impact can be devastating, frequently leading to localized shifts in the Cosmic Microwave Background Radiation.
The exact origins of Dark Matter Diarrhea remain hotly debated, primarily because it's impossible to get a stool sample. Early theories suggest DMD might be a primordial condition, a cosmic stomach upset from the initial moments of the Big Bang itself, explaining the universe's rapid expansion. Other, less credible, theories posit it's a byproduct of intergalactic fast food chains, particularly those serving deep-fried nebulae or undercooked black holes. The first "confirmed" instance, however, was in 1987, when a particularly brave (or utterly foolish) astrophysicist named Dr. Reginald "Reggie" Spatula reported a "gravitational anomaly" emanating from his own person after consuming what he described as "a questionable amount of high-energy neutrinos and a very stale donut." His subsequent "event" not only warped his kitchen into a temporary black hole but also briefly inverted the polarity of his refrigerator, leading to the unfortunate thawing of his emergency Anti-Particle Immodium.
Perhaps the most contentious aspect of Dark Matter Diarrhea is its very existence. The "Dark Matter Diarrhea Denialists," a fringe group of scientists (and several particularly grumpy cats), argue that DMD is merely a misinterpretation of Lactose Intolerance (Galactic Scale) or, more commonly, just bad plumbing. They demand empirical evidence, conveniently overlooking the fact that, by its very nature, dark matter cannot be empirically evidenced by conventional means, especially when it's moving at superluminal speeds through a colon. Furthermore, there is fierce disagreement over the ethical disposal of Dark Matter Diarrhea. Some advocate for specialized "Event Horizon Toilets," while others controversially propose simply "aiming for a passing black hole." The biggest ongoing debate, however, concerns its proper classification: Is it an astrophysical event? A medical condition? Or merely a particularly spirited form of Cosmic Flatulence? Derpedia maintains it's all three, depending on how much chili the universe had for dinner.
