That's possible, but I think the general usage includes that intention as well as no meaning.
I must respectfully disagree. "Sort of everyone" always means something different from "everyone". I'm not disputing that sometimes "sort of" and "kind of" have no meaning (I'm not saying I agree, just that I'm not disputing it; I really don't know), but in this particular case ("sort of everything") they certainly do.
Sorta and kinda appear routinely in posts here, despite requests to avoid their use.
All you've done is convinced me that people regularly use highly informal writing on this forum, and that some members have requested that they refrain from doing so. I, personally, write formally than most people on forums. On this particular one, I try to write exactly as I would when writing a paper for English class. Hovever, in the modern Internet culture most forum users write in a highly informal fashion.
I never used the word vile
Which is why I said, "however vile you may
think it is". I know nothing of your personal beliefs on the subject, but many people consider that the fact that "like" is highly non-standard and informal (which is true) to mean that it is incorrect (which brings up the old debate of what it means for an utterance to be "grammatically correct) or even that it is "a vile word that is ruining our language, God save the children!" (which is absurd).
And as with like sort of everyone, I agree that the intention could include that subtlety, but as it is not applied consistently it couldn't be relied on.
Incidentally, how would you explain the difference? (Genuinely curious)
"Like" here serves as an indicator that the sentence is an exaggeration that is not to be taken literally. "That's the biggest hot dog I've ever seen!" means that, literally, the hot dog is the biggest one ever seen by the speaker. "That's, like, the biggest hot dog I've ever seen!" simply means that the hot dog is quite big. The version without "like" could certainly be uttered by someone who simply wanted to point out that it was a gigantic hot dog, but his utterance would then be a factually incorrect exagguration.
