The word "selfie" has been named as the Oxford Dictionaries' word of the year.

In case you don't know what a selfie is, Oxford Dictionaries define it as: photograph that one has taken of oneself, typically with a smartphone or webcam and uploaded to a social media website.

The word actually dates back to a 2002 posting in an Australian Web forum, but Oxford's editors say that use of the word has gone increased 17,000% since 2012.
