At least 3 are movie references: “Damn it Janet” – Rocky Horror Picture Show, “Nobody puts Baby in the corner” – Dirty Dancing”, “we’re going to need a bigger boat” – Jaws
I think many popular phrases – at least in the seventies to the nineties came from movies, television and commercials. I suppose that was a new way youth consumed culture back then.
Your ass is grass was usually followed up with “and I’m the lawnmower” but I still hear some of these today (not in real life but on tv shows that I binge).
the only one I still hear occasionally — and it is from seniors, my brigade —- is ‘you sound like a broken record’ —
That’s amazing! I’d forgotten that one!
