Definition please?

I heard a random DJ (Random cause I don't know which one) this morning used the phrase buck naked.

What does that mean? Is buck more naked than naked? Oh she was hot and she was naked... too bad she wasn't buck naked. Ya... damn... That would have been cool.

One misguided streaker to another: "Oh you're going... and if you don't go I'm going to come back here and make you go and you'll go buck naked instead of just naked dammit, now get that jock off and start running we have a political rally to upset!" (Too bad they were running through the libertarian national get together in which nobody really cared.)

buck naked.

It sounds good. Maybe that's it. We just put Buck in front because it's fun to say. Like Y2K it's fun to say.

Or maybe it's a warning. People get upset when other people are naked. (unless they are naked too, but that's another story) So as not to surprise someone one adds buck in front of the word naked so as to warn the listener that naked will shortly follow because you never hear something like: He was running through the crowd buck happy with his pockets turned out and his tie loose. You never hear that. Never. It's always buck naked.

Why?
