There’s a scene in The Garden of Eden where the female character uses the word “paramour,” and the male lead reacts thusly, which is how I felt hearing these, too:
“You really said it,” David told her. “I’d never heard that word pronounced and I had absolutely no hope of ever hearing it in this life. You’re really wonderful.”
“It’s a perfectly common word.”
“It is at that,” David said. “But to have the sheer, naked courage to use it in conversation.”
Walter in The Big Lebowski says “Pederast” in normal conversation…
I suppose that’s a much shabbier moment of inspiration than paramour in Garden of Eden.
