The next time someone tells you to stop saying "interweb" instead of "internet," you can tell them it's in the dictionary. It's in the New Oxford American Dictionary, to be precise. And so are all the other terms we've been using online for years now, including LMAO, BFF, TTYL and defriend/unfriend.

This year's class of new words is like a tribute to the web culture of half a decade ago. The New Oxford American is the young, hip rebel of the dictionary world, and it still can't keep up with the internet's incredible rate of linguistic change. Does anyone else think it's an epic fail that they left out epic fail?
