Walking around looking sad, depressed, or listless; brooding without energy or motivation.
Origin uncertain, possibly from Scandinavian languages, first recorded in English around 1600; may be related to Dutch 'mopen' or Old Norse 'moppa,' meaning to grimace or pout.
Moping is that very specific human sadness—not dramatic crying, but the kind where you shuffle around the house doing nothing, staring at walls, which is probably why English speakers needed a special word for it!
