Being moody and refusing to talk or interact with others, usually because you're upset or angry about something.
Origin uncertain, possibly from Scandinavian languages. First appeared in English in the 17th century, possibly related to old words meaning to be slow or heavy in movement.
Interestingly, sulking might come from words describing physical slowness because when people sulk, they really do move more slowly and heavily, as if their mood is weighing them down—your body language actually matches the emotional meaning!
