sidesplitting
UK: ˈsaɪdˌsplɪtɪŋ | US: ˈsaɪdˌsplɪtɪŋ
adj. extremely funny; causing uncontrollable laughter
The word "sidesplitting" combines "side," referring to the lateral part of the body, and "splitting," suggesting forceful division. The imagery evokes laughter so intense it feels as though one’s sides might burst—a hyperbolic metaphor for humor. The term emerged in the early 19th century, reflecting English’s tendency to create vivid compound adjectives.
