Once upon a time, two words met and fell in love. One was called immigration and the other was called invasion. They had a common interest in large groups of people moving around, and on the basis of this they decided to get married and settle down, quickly producing an offspring called immivasion. This young child naturally shared characteristics of both parents, and seemed to have a bright future describing the demographic confusion of an increasingly over-globalized world.
But before immivasion could properly grow up to be a fully mature word, and included in all the big, official dictionaries, the naive young thing went for a walk and ran into a much older and often evil word, Muslim.
He had successfully obscured much of his dark past by having his etymology "delisted" so that few people actually knew what he meant. When asked to define himself, he invariably said he was synonym of peace, a particularly popular word at that time.
Muslim, by praising the young, immature piece of vocabulary and giving her a ride in his car, while plying her with various sedatives and stimulants, finally managed to have his wicked way with her. After several vigorous "compoundings" immivasion finally bore a child, a new word called Muslimmivasion.
Understandably, young immivasion's life was ruined by being "compounded" at such an early age and the poor little word soon afterwards took her own life by hanging out too much on the internet.
But the offspring of this unholy union, Muslimmivasion, appears to be doing well, getting a major boost from the collapse of Middle Eastern nations, the prolapsed borders of Europe, and the rampant moral signalling of many left-wing Europeans.
It is for this reason that respected etymologists have been predicting a dazzling future for the young piece of vocabulary in denoting the increasing and unwilling Islamization of Europe, something that is sure to become a dominant feature of the next few decades.
