A person who jokes around, does silly things, or tries to make others laugh in a disruptive or annoying way.
From 'cut' + 'up' (to behave badly or perform antics). Emerged in American English in the late 19th century as slang for a show-off or jokester.
Before 'cutup' meant a joker, 'cutting up' meant literally destroying things through misbehavior—the word evolved from destructive chaos to playful chaos as applied to people.
