Aye, I thought we had, can’t imagine there’s anyone else who can summon such ire on the subject 😆 The meaning’s completely the opposite, and that there’s a perfectly good alternative source for it, so I can’t see any reason why you’d think people using the term are trying to make a CO link. It’s just a coincidence.
Best known use of it- Rocky Horror Show. Name inspired by late night horror film showings, not by Burgess- the fact that it came after doesn’t make any difference.
And let’s be honest here- nobody’s read Clockwork Orange, practically nobody’s seen the film, and even those that have mostly don’t remember much of the language, and those that do mostly don’t care 😉
