Buck naked, butt naked

No one knows the exact origins of buck naked, which means completely naked, but the American Heritage Dictionary says it’s from the U.S. South. The earliest example we can find in historical Google News searches (which of course are very limited) is from 1915, and the term gradually becomes more common as the century progresses.

Despite what some sources say, butt naked is not wrong. It’s just a newer form. Even that is disputed, though, as some have conjectured that the buck in buck naked was originally an alteration of butt. Still, the earliest instances of butt naked we can find are from the 80s.

Plus, both buck naked and butt naked are slang terms, and you’re not likely to see either used in earnest in any type of formal text. When it comes to slang terms, colloquialisms, and idioms, questions of right and wrong are irrelevant because these things by definition don’t conform to any so-called standard English. So if you’re going to use buck naked or butt naked, it’s safe to use the one you like better.

On the web, butt naked is more common than buck naked by a ratio of about three to one. In searches covering edited content, though, buck naked is far more common, which suggests that many writers and editors consider it the more acceptable form.

  1. “Butt naked” is probably used more by those under, say, 40 years of age; thus, it’s no surprise it’s on the web more.  “Buck naked” is the older form, thus most used currently by those in editorial control as these folks are probably over 40. 

    I’d always heard that it had to do with “bucks”–boys or young men–being naked–as in the case with a “stripling” in Roman days. For Native Americans, it was probably common to have few clothes until a certain age, especially in the summer. For enslaved African-Americans, it may’ve been connected with poverty for youngsters, but may also have to do with degrading nudity or near nudity at slave auctions. 

    • since it says the origin is the US south, i thought maybe ‘buck’ like male deer, like naked as a buck.

  2. IMHO, it seems to me that “butt naked” is short hand for “with (his,her) butt naked. Example: He sprinted, with his butt naked, down the stairs. or He sprinted, butt naked, down the stairs. In this case “naked” is an adjective modifying the noun “butt”. “Buck naked” seems more likely to have come from the simile “naked as a buck”. I tend to agree with Ebd2140 on the source and intent of buck. One can easily imagine this simile evolving into “buck naked”, the simile “naked as a jaybird” evolving into “jaybird naked”, or the simile “smart as a Jeopardy contestant” evolving into “Jeopardy smart”. Dissenting opinions are most welcome.

  3. I have always thought it was Buck Naked, like a male deer because that is the state of a deer. But I see Ebd2140’s point about young male humans being referred to as bucks.

    I have always thought the use of the word Butt is just a misunderstanding of the original term. That version of it has never made sense to me, because saying your butt is naked conveys less information than just saying you’re naked.

    Not arguing with any information, just relating what I have always thought about it.

  4. My grandmother, who was born in May of 1900, used to say “buck naked”. When I was very young, 10 years or so, I said, “What’s ‘buck naked’? and I remember her answer. She said, “It means that you are as naked as a buck deer.” With that in mind, I would believe that the original saying would be “Buck Naked”, due to the difference in proper language, at the early 1900s. People did not use foul language in “mixed company” or in proper society. To use that type of language was never done in public. Use of the word “butt” would have been as vulgar, in those days, as the “F” word, in today’s society.

  5. “Butt-naked” is wrong. It’s a mass-misunderstood/misheard phrase that has somehow been accepted as an alternative for the correct phrase, “buck-naked”.

  6. I haven’t read all your comments but when I hear the expression ‘buck naked’ I think of money. Someone who does not even have one dollar…now I am Dutch. This is probably one reason why this expression reminds me of money ;-)
