KILLCROP — [Noun] A voracious infant, especially one believed in folklore to be a fairy changeling. Borrowed from Low German kīlkrop, from kīlen ("to torment, to tease") + krop ("crop, craw"), hence literally "one who torments the crop/craw," alluding to insatiable hunger. Unlike a changeling, which implies a covert substitution, or a gourmand, which suggests a connoisseur of excess, the killcrop is pure, unsocialized appetite in a cradle. It is the ceaseless cry that empties the larder, the ancient stare in a pinched face, and the cold dread that the child consuming your substance is not your own—a stark reminder that the most profound fears are those that devour us from within.
