: I am interested to learn of the derivation of the phrase "what's that when it's at home", where 'that' can be a word that the speaker/writer does not understand the meaning of.
: with thanks
Eric Partridge, "A Dictionary of Catch Phrases American and British," has an entry for it but doesn't say where it came from.
"What is that" (or "what's that") "when it's at home?"; and "who is he" (or "she") "when he's" (or "she's") "at home?" C20 tags, implying either derision or incredulity, and signifying 'I've never even heard of her, him, it'. Edwin Pugh uses it in 'The Cockney at Home', 1914, and Dorothy L. Sayers in 'Have His Carcase', 1932, has: 'Haemophilia. What in the name of blazes is that, when it's at home?' . . . It is, in short, directed esp. at someone employing an unusual or erudite or highly technical or scientific term in a milieu unlikely to know its meaning.
