Yes, obviously I realized there's a precedence. And that has often gone on to lead to more stupidity and ambiguity. Look at the word literally. It literally does not mean literally anymore and this literally is a sentence that doesn't make sense.

Words mean something for a reason. If you change the meaning of words then they don't really mean anything. How about we change go f*** yourself to actually mean you look great today? Do you think this could cause any confusion and problems? What about racial slurs? Can we say that they mean flowers and bunny rabbits now and that's okay? What if we change the word stupid to actually mean smart? Words mean something for a reason. And by switching them around at whim all you're doing is degrading human language and what it means.

No, you really can't.
