The ‘Concise Oxford English Dictionary,’ celebrating its 100th birthday this year, has added 400 new entries to the English language.

The freshman class of words that are now officially, well, words include “sexting,” “retweet,” “mankini,” “noob,” “jeggings,” and “woot.”

In a blog post, Angus Stevenson from the Oxford University Press said, “Sadly, the new edition has no room for tremendous words like brabble ‘paltry noisy quarrel’ and growlery ‘place to growl in, private room, den’ – what we might call a man cave these days. But the preoccupations of today’s Generation Y have opened the door to some equally colourful vocabulary.”

We don’t know about you, but “growlery” is pretty awesome. We’d have given up “mankini” for that.
