Re: They guessed the acronym.
[Adding the prefix "ir" to "regardless" gives you a word that means "without a lack of regard" - that is, "regard". It is a single word double-negative that negates itself, and thus simply an ignorant use of language, not a novel and creative one as the examples you gave are.
Ah, but that's another example of the mutability of the laws of english morphology, phonology and syntax. There was no precedent for the "double negative" or the "split infinitive" in English. These were rules of Latin which, when English was being standardised in the 16th / 17th C, various scholarly types, liked. So when writing their prescriptive Grammars, they included these rules and the ignorant masses (our ancestors) adapated their speech patterns, for the most part, to these new prescriptive rules.
I used to feel as strongly as you do about people using language incorrectly, but studying English language (and it's use, history and variations around the world) has shown me that one shouldn't judge, merely study and observe.
An example of this is the Scots language (or dialect, depending on your stance...). In Scotland, Scots, or the broad dialect of Scots English (again, depending on your take on the "language/dialect position), has a lower percieved status than SSE (Scottish Standard English); but this is a socially constructed opinion; there is no reason for the one language to be regarded with any less prestige than the other.
Indeed, because Scots and English are so similar, it's easy to view someone using Scots as using "bad English"; many people do. In fact, I used to! My old boss used to say "youse" as a plural to you. (e.g. "Youse lot come over here!")
And I, as the literate, educated, and slightly arrogant employee (
) would correct him mercilessly. Imagine my surprise to discover that this was a trait of Middle English which was dropped over the years due to the laziness of general english speakers, but which was still extant in Scots.
Doh!
Indeed, many of the characteristics of Scots were once present in English, and have remained here as it is a more conservative language / dialect. Jings, crivvens and help ma boab! Hoots mon! And all that.
Any living language, i.e. one that is in use, is always changing. Today's counter intuitive idiot-slang (and I'm not arguing with you that most of these are both stupid and counter-intuitive) will become tomorrow's accepted use of the language.
