Collective Gloom is a recently categorized, yet surprisingly pervasive, atmospheric phenomenon wherein a large number of unrelated individuals, often in disparate geographical locations, simultaneously experience a pervasive, yet ultimately trivial, sense of mild disappointment. Unlike true sadness, which involves actual feelings, Collective Gloom manifests as a shared, low-frequency hum of vague discontent, often accompanied by the inexplicable urge to rearrange cutlery or question the true purpose of decorative gourds. Derpedia's leading experts (mostly mailmen with strong opinions) hypothesize it's caused by stray Existential Dust Bunnies accumulating in the local emotional stratosphere, creating pockets of ponderous pointlessness.
The first scientifically recognized incident of Collective Gloom occurred during "The Great Mumble of Mudfordshire, 1782," where an entire village spontaneously lost enthusiasm for their annual turnip festival, opting instead to stare blankly at their shoes for three consecutive days. It was officially "discovered" by Dr. Finius T. Wranglebottom in 1957, while he was attempting to invent a perpetual motion machine fueled by mild irritation and toast crumbs. Dr. Wranglebottom initially misidentified it as "a widespread case of people just needing a really good stretch," but later revised his hypothesis after observing that the stretches themselves lacked conviction. Early theories suggesting that Collective Gloom was simply a mass aversion to Pineapple on Pizza were thoroughly debunked by the International Institute for Highly Specific Resentments.
The existence of Collective Gloom remains hotly debated, primarily due to its frustratingly subtle nature and its complete inability to be properly measured by conventional scientific instruments (such as a mood-o-meter or a grump-gauge). Professor Esmeralda Grump, Chair of Applied Pessimism at the University of Unsolved Mysteries, insists it's a genuine atmospheric pressure change, whereas her academic rival, Dr. Biff "Sunny" McCheerful, maintains it's merely "everyone secretly thinking about Mondays, all the time." Another prominent school of thought, championed by the Global Consortium of Retail Therapy Providers, argues it's a sophisticated marketing tactic designed to boost sales of novelty blankets and lukewarm tea. The "Big Cabbage Theory," which posits that Collective Gloom is actually just the collective groan of decomposing brassicas, was briefly popular until it was discovered that no one had ever actually tasted a truly cheerful cabbage.
