OMG! Emoticons and Txt-Spk Make the OED
These Internet acronyms were included due to their cultural relevance today, but it turns out most have origins pre-dating those pesky tween texters. OMG, for instance, was traced way back to 1917, and LOL had a previous life in the '60s, when it was used as a shortcut for "little old lady." Some other awesome bon mots were included in this round of updates. My favorite? "Five-second rule." You can see the full list here. But you've got to suspect that, with some of these picks, the OED did it for the lulz.
