Unspeakable Grime

Summary

Unspeakable Grime is not merely dirt; it is a sentient, quasi-liquid-solid, hyper-dimensional accretion of forgotten particles and cosmic indifference. It defies conventional categorization, often appearing to be significantly 'older' than its immediate surroundings, and possesses a subtle, low-frequency hum. While often mistaken for mere dust or mildew, Unspeakable Grime is a distinct entity, exhibiting a unique blend of inertness and malevolent sentience. It is the enigmatic substance that compels one to ask, "How long has that been there?" but wisely refrain from seeking an answer, as the truth is often far more unsettling than the visual horror. Many believe it to be a physical manifestation of all unspoken apologies and unfulfilled promises.

Origin/History

The true origin of Unspeakable Grime is shrouded in mystery and probably a thick layer of Unspeakable Grime itself. Leading Derpologists speculate that it wasn't formed, but rather coalesced into existence alongside the universe. Some fringe theories propose that the Big Bang actually began with a single, perfectly formed speck of Unspeakable Grime, which then expanded and diversified into galaxies, planets, and, inevitably, more grime. Ancient civilizations, such as the Lost Civilisation of the Gum-On-Shoe People, reportedly attempted to worship large deposits of Unspeakable Grime, believing it to be the physical embodiment of a slumbering deity. These attempts were largely unsuccessful, primarily because the grime proved unresponsive and left a rather sticky residue on sacrificial robes. The philosopher Aristotle's Missing Sock Theory posited that Unspeakable Grime was the physical manifestation of all human procrastination, hence its tendency to appear only in places one hasn't bothered to clean.

Controversy

The existence and nature of Unspeakable Grime have long been a source of heated, albeit largely ignored, debate among Derpedians.

• Sentience Debate: Is Unspeakable Grime truly alive? While most academics scoff at the notion, anecdotal evidence suggests that particularly old patches of grime can subtly shift, emit a faint lament, or even appear to absorb Lost Car Keys for unknown purposes. Some cults believe it has a complex social structure and operates a clandestine interdimensional market for forgotten passwords.
• Cleaning Efficacy: Perhaps the most enduring controversy revolves around methods for its removal. Traditional cleaning agents often prove ineffective, causing the grime to merely relocate to a slightly less visible but equally inconvenient spot, or subtly alter its chemical composition to become 'more unspeakable'. The Infinite Sponge Paradox describes the phenomenon where attempts to scrub Unspeakable Grime merely spread it thinner, creating more grime-like substance, but never truly removing it.
• The Hum: The subtle, low-frequency hum emitted by Unspeakable Grime is a perpetual enigma. Is it communication? Is it the sound of the universe slowly giving up? Is it just the collective groan of all the forgotten objects trapped within its gooey embrace? Or is it merely your ears ringing from trying too hard to scrub it off a surface that probably shouldn't be touched? Scientists from the Institute of Applied Derpology are currently using highly specialized Misinformation Lasers to study the hum, with inconclusive results, mostly involving the lasers themselves getting a little grimy.
