leotard: [19] The leotard commemorates the French trapeze artist Jules Léotard (1830–70), who wore such a garment when he was performing. He was one of the foremost circus acrobats of his day, and a pioneer of aerial stunts: he performed the first mid-air somersault, and invented the ‘flying trapeze’ (he became known as the ‘Daring Young Man on the Flying Trapeze’, from George Leybourne’s song (1860) of that name), but fate has decreed that his name should be passed down to posterity in the form of a one-piece exercise garment.
barnstorm (v.)youdaoicibaDictYouDict
1815, in reference to a theatrical troupe's performances in upstate New York barns (usually featuring short action pieces to suit vulgar tastes); extended 1896 to electioneering, 1928 to itinerant airplane pilots who performed stunts at fairs and races. Related: Barnstormed; barnstorming.
cheese (n.2)youdaoicibaDictYouDict
"the proper thing," from Urdu chiz "a thing," from Persian chiz, from Old Persian *ciš-ciy "something," from PIE pronominal stem *kwo- (see who). Picked up by British in India by 1818 and used in the sense of "a big thing" (especially in the phrase the real chiz).

This perhaps is behind the expression big cheese "important person" (1914), but that is American English in origin and likely rather belongs to cheese (n.1). To cut a big cheese as a figurative expression for "look important" is recorded from 1915, and overlarge wheels of cheese, especially from Wisconsin, were commonly displayed 19c. as publicity stunts by retailers, etc.
The cheese will be on exhibition at the National Dairy Show at Chicago next week. President Taft will visit the show the morning of Monday, October thirtieth, and after his address he will be invited to cut the big cheese, which will then be distributed in small lots to visitors at the show. ["The Country Gentleman," Oct. 28, 1911]
stunt (v.)youdaoicibaDictYouDict
"check in growth, dwarf," 1650s, from verb uses of Middle English adjective stunnt "foolish," from Old English stunt "short-witted, foolish" (as in stuntspræc "foolish talk"), from Proto-Germanic *stuntaz (source of Old Norse stuttr "short"). Related: Stunted; stunting.
