Novak Djokovic and Rafael Nadal battled in this year's US Open final on September 9, 2013. At one point during the match the camera focused on Nadal's girlfriend, who was watching from the stands. Oh - no wait: It was Nadal's girlfiend. Urban Dictionary's top entry for girlfiend is this definition: "A girl who's your friend but treats you like a boyfriend without the
positive benefits. Such as sex, emotional support and compassion."
