Demenish

Demenish: verb. A sociogeographical phenomenon where the ratio of men in a population decreases rapidly for unknown or inexplicable reasons. The word was first used by the renowned illiterate theologian John Savage in his seminal 1845 work, "Figs and such", where he referred to the sudden change in the behavior of oxen, "The population of locusts in Kent has been suddenly demenished, which has led some to speculate about the potential implications for combine harvesters."
