Michelle Obama shared one with her "first dog" Bo, Hillary Clinton tweeted one with her daughter Chelsea. Now "selfie" -- the smartphone self-portrait -- has been declared word of the year for 2013, according to Britain's Oxford University Press.
The publisher of the Oxford dictionaries said Tuesday that "selfie" saw a huge jump in usage in the past year, bursting from the confines of Instagram and Twitter to become mainstream shorthand for any self-taken photograph.
Researchers behind the renowned dictionaries pick a prominent word or expression in the English language each year that best reflects the mood of the times. Previous words of the year have included "unfriend" in 2009, "credit crunch" in 2008, "carbon footprint" in 2007 and "Sudoku" in 2005.
