The only time I heard the word "lox" was when I was a kid and had the James Bond film You Only Live Twice on VHS. This is the one where Blofeld is launching rockets from Japan to destroy Soviet and American spacecraft, with the hope of them blaming each other and triggering a war. For some reason, one of the scenes that stuck in my mind was when the head of the Japanese intelligence services (Tanaka?) and Bond are reviewing the receipts that the latter managed to steal from the company they suspect is acting as a front for Spectre. Tanaka is reading out a perfectly innocent list of items and comes across a huge order for "lox", and asks Bond what that means. At first he just defeatedly dismisses as an American word for smoked salmon, but then has a brainwave and says something like "But... it can also be a shorthand for Liquid Oxygen, which is needed to power rockets!".
