Woot! The Concise Oxford English Dictionary 12th edition is here...

The Concise Oxford English Dictionary is celebrating its 100th birthday!

And woot actually made their list of new words in the 12th edition. For the 2 people out there who don’t know what woot means, it’s used to express elation, enthusiasm or triumph online or on Twitter. Speaking of Twitter, the word retweet is now official – it’s a verb – and it means tweeting a tweet someone else already tweeted. If you don’t know what a tweet is, you’re way behind. Here are a few more new entries in the 12th edition:

• Mankini: n. a brief one-piece bathing garment for men, with a T-back.

• Jeggings: pl. n. tight-fitting stretch trousers for women, styled to resemble a pair of denim jeans.

• Sexting: n. informal the sending of sexually explicit photographs or messages via mobile phone.

Even some old words wound up with new definitions. A “cougar” is no longer just a variety of cat, a “friend” now has social networking implications – and a "follower" could be someone who’s far, far away.
