Way back when I was teaching fifth grade, I remember chastising a student for littering her paper with acronyms like TTYL and LOL. I have nothing against acronyms. As a matter of fact, I think they’re rather cute and useful. I’ve even made up several of my own, like MLB. I made this up at the gym when there was a bald man with a perpetual scowl. He would drop his weights – a gym no-no – and grunt loudly, as if to announce his strength. He became MLB, which stood for Mean Looking Baldy.

We are all familiar with GIF, but what does it mean? What about SCUBA?
