Today, the Oxford Dictionaries Online added the term "twerk," along with "selfie," "badassery" and more than 60 other slang words, to its online dictionary, Time reports. Why now? Time says they have become a symbol of culture as it is today, and we also believe we have Hollywood to thank for their relevance. Rihanna regularly defines what badassery looks like, while Beyonce and Selena Gomez have perfected the art of the selfie. And need we remind you of Miley Cyrus bringing "twerk" into the spotlight with her recent MTV Video Music Awards performance with Robin Thicke? We may be most excited about "selfie" officially entering the English lexicon, because we think the trend has way more staying power than "twerking" ever will. (Sorry, Miley!) With that said, check out our tips for taking the perfect selfie below.
