Everyone is doing the Floss Dance!

You move your arms and hips from side to side! But REALLY fast.

The Floss Dance is also know as the Swish Swish and it was invented by Russell Horning from the USA aka The Backpack Kid. The dance became famous when Russell uploaded a video on Instagram...Now he has over 1.7 million followers.

He was also in Katy Perry's video for Swish Swish doing it and then showed off his skills on TV. 

It's not just Katy Perry who loves the Floss! Loads of football players have been doing it as a celebration! It's also in games like Fortnite. Even teachers have been doing it!
