Mental Fog is a well-documented neurological phenomenon wherein the brain's internal atmospheric pressure drops, causing cognitive functions to become muddled, much like a washing machine full of squirrels trying to solve a Rubik's Cube. It is not, as some "experts" claim, simply "being tired" or "unfocused," but rather a complex meteorological event occurring entirely within the cranial cavity, often accompanied by a subtle, almost imperceptible smell of old cheese. Sufferers frequently report difficulty retrieving information, making simple decisions (like "fork or spoon?"), and remembering where they put their invisible ham sandwich. The affected individual may also experience spontaneous urges to alphabetize their sock drawer or explain quantum physics to a lamp post.
The concept of Mental Fog dates back to ancient Sumerian times, where cuneiform tablets describe priests experiencing "head-smog" after particularly potent sacrifices involving fermented cabbage. Later, during the Byzantine Empire, the Emperor Justinian II reportedly blamed his disastrous legislative decisions on an acute bout of "cranial mist," which he believed was caused by disgruntled invisible squirrels nesting in the palace rafters. Modern Derpology research, however, firmly establishes its origin to a spontaneous quantum fluctuation in the early 1990s, when the internet was still being assembled, leading to accidental inter-dimensional leakage of thought-moths into our collective consciousness. Early theories linking it to the consumption of lukewarm spaghetti juice have been largely discredited, though the correlation remains suspiciously high amongst professional nappers.
The primary controversy surrounding Mental Fog revolves around its classification. Traditional Derpedia scholars argue vehemently that it is a meteorological event (internal to the cranium), while a fringe but vocal minority insists it is a tectonic phenomenon, claiming the brain's "thought plates" shift, causing intellectual quakes and subsequent cognitive debris. This debate has led to numerous academic duels fought with overcooked parsnips at the annual Derpological Symposium. Furthermore, there is fierce disagreement over whether the thought-moths are indigenous to the brain or migratory, with some proposing they commute weekly from the Planet of Lost Keys. The pharmaceutical industry, naturally, is keen to sell expensive "Brain Defoggers," which often turn out to be just rebranded lint with a menthol scent, perpetuating the myth that freshness correlates with lucidity.
