Meet 18-year-old Sheryse Skinner, a university student from Perth, Western Australia.
Skinner told BuzzFeed that she created a dance challenge based on Exo's music video Ko Ko Bop.

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. "
This is the dance move the challenge is based on.
She said she posted the video in July and forgot about it until it started to go viral recently.
Last week, Skinner's dance crew KCDC did the challenge when it started to go viral.
People have been recreating Skinner's video since.

Skinner said she's glad people are enjoying the challenge.
She added, "Also, like other people, I think this is a really good way to make people know about Exo who may not have heard about them before.
"I didn't necessarily make this with a purpose for it to spread all over the world. I just thought it was relatable to the few followers I had at the time."
