When the District’s AlertDC emergency messaging system sent this warning out last night, the advisory about this weekend’s impending triple-digit temperatures was met with ridicule and mockery.

Here at DCist, we’re admitted word geeks — so whenever an organization tries to give us some new words to tool around with, we get kind of exciting. (Call blogging nothing more than roustabouting, and we’ll have words, you hear?)

There was quite the hubbub among Washington journalists about the Associated Press’ recent decision to remove the hyphen from “e-mail” in its stylebook. But I’d argue that the list of annual additions to the Oxford English Dictionary is of far wider importance. As always happens with a list of new words, there are some surprises (why were banh mi or headline not in the OED before?), some words that will ruffle a few feathers (did the religious among us needed Second Coming defined?), additions which feel pretty dated (muffin top — slightly behind on Seinfeld, are we, guys?), and new words which you know that the editors are just putting in to mess with us (wassup).
