What do you call an outer garment covering the body from the waist to the ankles, with a separate part for each leg? The referentially and socioculturally least restricted lexical item for this purpose, in both AmE and BrE, is the plural noun trousers. (The gloss in my first sentence is in fact the definition of trousers given, without restriction, in NOAD.)
It’s then remarkable that the Quite Interesting Twitter account maintained on 8/14/18 that
The Victorians thought the word ‘trousers’ so vulgar and rude that they used euphemisms such as ‘sit-upons’, ‘inexpressibles’, ‘unutterables’ and ‘unwhisperables’ instead.
The result of such an attitude would have been that there was literally no everyday expression to refer to such a garment — even one originating as a euphemism but naturalized as ordinary vocabulary — as has been the case for white meat as a replacement for (chicken) breast, for some speakers, and in many other cases.
