What are the acronym, internet words like lol, brb, imho, etc., called? Is there such a term beyond acronym? I was wanting to tell someone that someone else was not familiar with the meme/internet jargon/acronym 'M8' (or mate), but couldn't think of a reasonable word to use.
So, is there a term that would define these terms for how they are different than other, regular english 'SMS text'. Moreover, we find these terms more and more in the wild and not necessarily even on electronic devices, like on t-shirts or even spoken.
If I e-mail the message, "I'll be leaving the office at 10, but then I'll brb." What would I call the 'brb' part of the message, apart from the rest? "He e-mailed his boss a message saying 'He'd be right back', but he decided using an [internet jargon] was acceptable."
Although I have accepted an answer for now, I think it is inadequate, and that a word will eventually be coined to define these text terms. Until then...
