Why this word is great
GRASSATION — [Noun] A wandering about with evil intentions; a rioting. From Latin grassātiō ("rioting"), from grassāri ("to rage, riot"). Unlike "rampage" (which implies uncontrolled violence) or "pillaging" (which fixates on looting), grassation is the slow, deliberate prowl of malice—a predator circling a village at dusk, a gang idling through empty streets with coiled fists, or the way shadows lengthen and twist just before the first stone is thrown. It is the quiet before the storm, but the quiet is already guilty.
