It's just modern slang as a result of new technology.
To me, it's no different then how "text speak" slang came about.
I remember my parents being cross about the destruction of language because of "r u ok", "omg" and "lol" or "I h8 u" 😁
But now it's part and parcel of everyday language. Some people still use it, some don't. I've caught my parents sending an occasional OMG.
We've just become our parents and now we are the ones complaining about this new slang.
For anyone who is under the age of 20 and doesnt know what im talking about, back in the old days when mobile phones became affordable, they were very basic. We didn't have cool mini keyboards like we do on our smart phones.
Instead only had the number key pads and each number was allocated 3 letters.
To type a SMS message, you had to keep pressing the right number until you got the letter you wanted.
It took bloody ages to write a text message.
So, text speak evolved so it would be quicker.
