That "Twerk Team Captain" shirt you bought ironically on the boardwalk in Wildwood last month is, like, so over because "twerk" has been added to the Oxford Dictionaries Online. We feel comfortable blaming Miley Cyrus for this, too.
The official definition lists "twerk" as a verb meaning, "[to] Dance to popular music in a sexually provocative manner involving thrusting hip movements and a low, squatting stance."
Though the exact origin of the "word" is up for debate, Oxford Dictionaries' Katherine Connor Martin says that it's some 20-years old.
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," Martin said. "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.
In addition to "twerk," the folks doing the Lord's work for Oxford also made "selfie," "srsly," "FOMO," and a slew of other terms that DEFINITELY SHOULDN'T BE ACTUAL WORDS.
Seriously, "selfie" is considered a word. The end is nigh. [Washington Post]
