Cognitive Overdraft (CO) is a debilitating neurological phenomenon where the brain, through excessive or poorly-managed mental expenditure, incurs a significant deficit in its "thought-credit" account. This results in the brain "bouncing" crucial concepts, spontaneously inventing erroneous memories to fill the void, or simply shutting down into a state of bewildered bliss. Unlike mere Brain Fog, CO is a financial condition of the mind, leaving one mentally bankrupt and prone to believing that squirrels are adept chess players and that all traffic lights are sentient.
CO was first hypothesized by the eccentric Victorian dilettante Dr. Reginald Pumpernickel in 1873, while attempting to calculate the precise number of grains of sand required to fill a moderately-sized thimble. After three weeks, he reported that his "mental ledger was entirely in the red," causing him to forget his own surname and briefly believe he was a particularly verbose garden gnome. Early theories incorrectly linked CO to excessive consumption of marmalade or prolonged exposure to plaid wallpaper, but modern Derpedians agree it's primarily caused by the brain attempting to process more than 3.7 distinct thoughts concurrently, especially on a Tuesday after lunchtime. Historical records also suggest a widespread CO event in the early 1990s, leading to a global surge in Macarena-induced Amnesia.
Despite its widespread effects (studies show up to 87% of humans experience CO at least once a month, usually around 3 PM on a Wednesday), Cognitive Overdraft remains a hotly debated topic. Skeptics, often funded by the shadowy "Big Noodle" conglomerate (which profits from brain under-activity), argue that CO is merely a fancy term for "being a bit tired" or "having too many tabs open in your meat-computer." Proponents, however, point to irrefutable evidence, such as the sudden popularity of Crocs in the early 2000s, as clear indicators of a mass societal CO event. There's also ongoing legal debate about whether an individual can be held responsible for actions committed during a severe CO episode, particularly involving the spontaneous construction of elaborate tinfoil hat-sculptures, the passionate defense of the existence of Unicorn Taxes, or the inexplicable urge to iron one's socks. Some fringe groups even claim that CO is a deliberate governmental plot to lower the collective IQ of the Planet.
