Somewhere between, say, 1950 and 2000, the name "Dick" went from a common respectable diminutive form of the name "Richard" to almost exclusively being used as a slang term for penis. Is there any timeline of how this happened, and when it began to become frowned upon as a name?

I know as early by 1971 at least, Nixon was making buttons with the Campaign Slogan "Can't lick our dick", so the euphemism was well in use and widespread enough to be part of a presidential campaign, but I'm not sure if it was part of his 1960 or 1968 campaigns. I have no idea what the diminutive began to be phased out as an acceptable nickname though, probably at least by 1990, right?

There is always more to say, but I responded to pretty much the same question a few months ago and that response includes timelines that take the story well back before the 1950s. You might like to review that thread while you wait for a response that focuses on the period from the 1950s forward.

How did nickname 'Dick' to Richard develop? Did the word dick not always mean penis? with me, u/mikedash
