What do you call that texting shorthand that relies heavily on abbreviations (RU OK?) and initials (BTW/KWIM)?

I just came up with one I think is original, and whether or not it is, it is supremely appropriate for me: RAFTS

As in, Random Advice From a Total Stranger.

The internet seems made for this: we’re all throwing out RAFTS at some time or another, me (I suspect) more than many.

So there you go.  If it’s new and spreads across the net (“Hope you don’t mind RAFTS, I was just hoping it might help”), you’ll know where it started.

Or you’ll laugh at how slow I am to catch on. {shrug} As long as it’s not in my face…
