Your willful denial that a word can have more than one meaning (shock horror) doesn't make your false equations any more accurate.
I don't think that's what's going on. For example, what exactly would you suggest is the "alternate meaning" of fuck?
Example 1 "Fuck you."
What exactly does that mean? It doesn't mean 'I don't like you.' It doesn't mean "I'm angry with you." What does it mean? I don't even know. I don't think it even has a meaning. It's like shouting "GRGAGAHGAHHAHAHAHAH!" at someone. There's no real meaning, it's simply a venting of raw emotion.
Example 2: "I'm fucked."
What exactly does that mean? Well, the intent is probably something along the lines of "Things will not work out the way I want them to" or "something very bad is going to happen." While still slightly vague, it's certainly more clear than in the "fuck you" exmple. But the meaning here is obviously not the same
Example 3: "What the fuck is going on?"
Again, what does it mean? It seems to have no meaning...but I guess it's serving as a general emphatic. It's like adding an exclamation point to the end of the sentence. No real meaning, just some sort of increase of intensity.
If you want more examples,
lists have been made by people other than me.
So what's this "other meaning" for the word fuck that you say I'm "denying?" I think it's pretty clear that
there isn't one. This isn't simply a word having an multiple meanings. It's people using a word that appeals to them on some gutteral level, and simply saying it a whole lot...just because.
Kind of like the smurfs. "Oh, smurf! I'm smurfing my way to a positively smurfy day!"
And just as juvenile. The word "smurf" doesn't mean anything. Neither does fuck. If I went around saying smurf all the time people would think it childish. Do you see why I might consider it childish to say fuck all the time?
