The Gwiyomi Song, or Kwiyomi Song , is a K-pop single by South Korean singer Hari and was released on February 18, 2013. It was inspired by a gesture from South Korean rapper Jung Ilhoon of boy group BtoB. The gesture is called 'Gwiyomi Player', that was popularized by South Korean variety show Weekly Idol through a segment called "The Aegyo Battle" (Battle of Cuteness) following Ilhoon's guest appearance on the show in October 2012. The song went on to be a viral success and an Internet meme after Korean Media outlet Sports Seoul uploaded a clip of Hari performing the gestures and singing the song. This video has since inspired many Asian netizens to upload their own versions onto the internet.
