Miley Cyrus made it famous no doubt, after her recent display at the MTV Video Music Awards. The word "twerk" has been added into the Oxford Dictionaries Online.

Other words like selfie, digital detox, bitcoin, BYOD, emoji, FOMO, geek chic, hackerspace, phablet, srsly and TL;DR, have also been added.

Twerk joins other popular cultural words that Oxford has introduced to its print or online editions in years. If you haven't been following, OMG, LOL, totes, lolz are real words already in the English language.

Twerk's definition is: "Dance to popular music in a sexually provocative manner involving thrusting hip movements and a low, squatting stance." Or in other words like this:

And then this:

This morning we posted that a teddy bear maker wants Miley Cyrus to stop twerking the soft toys. It's one of those things you're going to hope your daughter isn't caught doing in public.

The term originated in the 1990s, according to the new entry.

“There are many theories about the origin of this word, and since it arose in oral use, we may never know the answer for sure," Oxford Dictionaries' Katherine Connor Martin told the AP. "We think the most likely theory is that it is an alteration of work, because that word has a history of being used in similar ways, with dancers being encouraged to ‘work it.’ The ‘t’ could be a result of blending with another word such as twist or twitch."

Here are definitions of other words,  added to Oxford Dictionaries Online — not to be confused with the elder, more official publication, the Oxford English Dictionary:
  • Selfie: "A photograph that one has taken of oneself, typically one taken with a smartphone or webcam and uploaded to a social media website."
