Yahoo! News: "w00t," a hybrid of letters and numbers used by gamers as an exclamation of happiness or triumph, topped all other terms in the Springfield-based dictionary publisher's online poll for the word that best sums up 2007. For more, see the definition. And props to Chuck for the link - I would have hated to miss this one.

Finally, I can stop explaining the meaning of it to analog people. After, it looks like I've used it 419 times on this blog alone, dating all the way back to 2003... this post being one of my more favorites.

Of course, now that it is "mainstream" it'll probably get over used and die before the end of the year...
