I suppose, but it’s not presented that way in the dialogue:
SPOCK: Admiral, may I ask you a question?
KIRK: Spock, don’t call me Admiral. …You used to call me Jim. Don’t you remember? Jim. …What’s your question?
SPOCK: Your use of language has altered since our arrival. It is currently laced with, …shall I say, …more colourful metaphors. ‘Double dumb ass on you’ …and so forth.
KIRK: You mean profanity. That’s simply the way they talk here. Nobody pays any attention to you if you don’t swear every other word. You’ll find it in all the literature of the period.
SPOCK: For example?
KIRK: Oh, the collective works of Jacqueline Susann. The novels of Harold Robbins.
SPOCK: Ah! …‘The giants’.
(Sorry about the bad transcript, it was the first one I could find.)
I wouldn’t exactly call either Jaqueline Susann or Harold Robins to be examples of authors known to have excessive swearing in their books. The problem is that the punchline doesn’t work unless it’s those sort of authors and not authors of the time who did have extremely sweary books, like John Irving. So it makes it sound like everyone in the 23rd century is a prude who basically doesn’t swear.
And Kirk not understanding how ‘dumbass’ worked kind of cemented that in.
