I don't remember when I got my OED, I think it was a gift for ordering something or joining something else, maybe a donation. I got the compact two volume set with the magnifying glass in the little drawer at the top. I had no idea what I was missing before becoming the proud owner of an OED. It's stored with my other books in Ohio these days. But even in the age of the internet, there are many times each week I wish I had it sitting on a nearby shelf, the etymology alone is worth the weight of moving those monster tomes from place to place.
Recently I discovered some of the newer additions to the OED. I admit to being a bit surprised but then I remembered just how comprehensive it was. The OED now includes: LOL, FYI and yes even OMG!
Also added: donut hole, happy camper, la-la land, muffin top.
Further new entries include the five (or two, or three, or ten) second rule for retrieving and eating food that has fallen on the floor. Apparently, jelly side up has not made the cut yet, despite being a very important corollary to the ten second rule.
