Selfie

For Miley Cyrus, the bathtub selfie is almost like a rite of passage -- or a daily ritual. Either way, it was of the utmost importance that she officially introduce her brand-new pup, Emu, into her bubble-filled Instagram tradition.

After a yearly increase in usage of 17,000 percent, "selfie" was crowned 2013's Word of the Year by Oxford Dictionaries, following last year's winner "gif" and beating out the Miley Cyrus-endorsed "twerk," among others.
