Apparently this question was asked over a decade ago but, the answers given do not address my specific curiosity. Of course, years ago, no one said "butt naked". "Butt" was not a common word - "bottom" and "behind" sufficed in polite company.
I was curious if the change from "buck naked" to "butt naked" was specifically engineered by the media due to racial sensitivities?
To be clear: I have read the hypothesis that the origin of "buck naked" (in AmE) is from naked Native American males - who were often called "bucks". However, in my experience, the change from "buck" to "butt" started in the 1980's.
Yes, the American lexicon had relaxed to include more words that were considered "impolite" - but the fact that male, African American slaves were also called "bucks" made me wonder if the shift was intentionally pushed in media to obliterate the earlier form of the phrase.
