She said she created her K-pop dance Instagram account and wanted to cover the song, but that it had been released recently so she didn't know all the moves.
Skinner said: "I was actually talking to my sister about how I only knew the one dance move from the music video and I did it very over-exaggerated for her. She suggested that I just do that one move because I did it so funny and that was all I knew.
"When I was posting it, my sister also suggested to hashtag it as a challenge just in case anyone decided to do it. "
