Why does “what the fuck?” make no sense? 
Or does it? I mean translated literally it’d be like saying “what does sex?” or “what does have sex” as most people take the word fuck as an interpretation of intercourse…rough too :smack: …So back to point, it doesn’t seem like the brightest thing for everyone to just randomly say all the time for a surprised expression at something either weird or stupid. I mean, I’m culprit to this…even at work (I’m a waitress and all my coworkers swear like sailors too in the back, hard not to catch on). Want to clear this up for me please? 
Fuck in this context is used as a generic expletive and does not specifically mean sex. Hope that clears things up.
It is an exclamation, like “What the Hell!”, only stronger, or, indeed, like single word exclamations such as “Shit”, or, indeed, “Fuck!”. They don’t mean very much at all except that they indicate surprise coupled with anger, or at least dissatisfaction or puzzlement. Whrn someone exclaims “Shit!” or “Fuck” they are not talking about excrement or sex.
This is clearly a perfect place for George Carlin. I think the linked clip will explain all you need to know about the F word.
Audio only, but definitely NSFW (unless you work in a much more relaxed job than I do.)
Does anyone know for sure who the narrator on that clip is? That’s a classic one, and it’s been attributed to a bunch of different people, but it doesn’t sound like Carlin to me.
Idiom (noun)
: an expression that cannot be understood from the meanings of its separate words but that has a separate meaning of its own

Concur that here, fuck is interchangeable with plenty of other words. I have heard (and used) “What the what ?” in confusion before. Grammatically and literally meaningless, but semantically valid and expressive.
When you think about it, most usages of the word “fuck” don’t make much literal sense either, anyway. Like “Fuck you !” : it’s rather nice getting fucked once in a while, isn’t it ? Unless the fucker is fucking with you, of course. In which case, fuck that fucking asshole !
Here is another Youtube f#@k video. Pretty funny and definitely NSFW.
Oops. It’s (almost) the same thing that ski posted. :smack:
That’s the same one linked to before.
Not quite… 
OK, the video is different. Same audio, though.
Okay, now I’m curious as to where and how the phrase originated.
If I had to take a wild-ass guess, I’d guess it evolved from “What in the world…” or “What on Earth…” which led to “What in Hell…” which morphed into “What the hell” which was “strengthened” to “What the fuck”; but WTF do I know?
A friend of mine used to race moto-X. He said that, down in the flats, you could go as fast as you want. You could yank the throttle WFO. I asked, and he explained. “Wide Fuckin’ Open!”
Except when he explained it to his mom, and then it was “Wide Freakin’ Open.”
According to my dentist, WTF is “Where’s the floss?”
So, I don’t know what the fuck you guys are talking about!
And if you think about it for a minute, you realize that NONE of those expressions make literal sense.
I’ll tell you what it doesn’t mean, at least not anymore. And that’s the Wisconsin Tourism Federation.

More uses to worry about.
Where is Marc Maron when we need him?
What [whatever] …
… was that?
… caused that?
… does that mean?
… are you doing?
… did you do?
… possessed you to do what has to be the most foolish thing anyone on God’s green earth ever thought to do, after I specifically told you not to?
While we’re at it, can somebody explain WTF WTH means?
