Personally I've observed many meanings in use. As an adverb it means "figuratively" or "approximately". As a hedge word it more generally disclaims that what follows may be inaccurate or metaphorical. It's used in the place of "to say" or "to impart", filling in for the lack of a word which applies equally to text messages as to speech, with the implication (since it's a hedge) that the quoted speech is likely re- or paraphrased. It can be used as a mild intensifier, as in, "Okay, but, like..."; despite what you may think, simply adding weight to a phrase can and does alter it semantically. So it's a very versatile word, and there are other uses I've missed. And of course, it is used purely as a stall (er, a disfluency), though not heavily outside of a few dialects. All of this falls under the linguistic study of "discourse", the way humans talk in real-world communication with each other. In linguistics, rules of discourse are real and as important as rules of grammar. Nobody uses only "approved" words or meanings of words or interactions of words; the ideas human beings communicate are more complex than that. Having laid all that out, I'll say something you'll probably find challenging: the real reason you don't like it is because you don't know what it means. Which is of course the point of it, and the reason to label it as innovation.
