"selfie", a self-portrait taken by a cell phone camera, is the word of the year for 2013, as per Oxford University Press. "selfie" saw a huge jump in usage in 2013, emerging from Instagram and Twitter to become a popular word for a self-taken photo. Researchers pick a prominent word or expression each year that best reflects the mood of the times. Previous such words have included "app" in 2011, "unfriend" in 2009, "credit crunch" in 2008, "carbon footprint" in 2007 and "Sudoku" in 2005.
The choice has beaten others including " twerk," the sexually provocative dance move, "showrooming,"- visiting a shop to look at an item before buying it cheaper online and "Bitcoin," the digital currency that gained widespread media attention. "Selfie" was added to the online Oxford dictionary in August and is being considered for inclusion in the physical Oxford English Dictionary.
"selfie" was first used in 2002 on an Australian online forum, and the hashtag (hash)selfie appeared on Flickr in 2004. But its usage wasn't common until 2012, when it started being used in mainstream media.
