jitterbug

the word 'jitterbug' is a vivid american coinage from the swing era of the late 1930s. its first element, 'jitter,' likely evokes the energetic, shaking movements characteristic of the dance, possibly influenced by the slang term for nervousness or the 'jitters.' the second element, 'bug,' draws from an early 20th-century american slang sense meaning an enthusiast or fan, as seen in terms like 'camera bug.' thus, a 'jitterbug' was literally a 'nervous-energy enthusiast,' a person devoted to performing this frenetic dance. the term perfectly captures the lively, uninhibited spirit of the dance and its cultural moment.
