IT was one of the biggest crazes of the past 12 months - with everyone from sports stars, actors, presenters and Fortnite gamers getting in on the act.
Dubbed the new dab, the move got kids and teens dancing all over the world.
How do you do the floss dance move?
To do the floss dance move, you swing your hips in the opposite direction to your arms - which are in two fists.
After swinging your arms to one side, keeping them straight, you then move one arm behind your back, and bring it back out in front.
Your hips are swinging from side-to-side with each beat.
You then swing your arms out to the other side and repeat the same moves.
Start slowly, and then increase your speed as you get more confident.
Et voila! Parents, you're officially "down with the kids".
Don't worry if you struggle at first. It's harder than it looks, and requires A LOT of coordination.
Who is The Backpack Kid and why is he suing Fortnite?
The floss dance was invented by Insta-famous dancer The Backpack Kid, aka 16-year-old Russell Horning, who has 2 million followers.
He posted a video of himself doing the dance move on August 18, 2016, and it soon racked up tens of thousands of views.
School kid Russell, from the States, is known for his free-flowing dance moves and deadpan expression.
Several YouTubers followed suit with similar videos.
Then on May 20, 2017, The Backpack Kid stole the show on Saturday Night Live, as he did the dance to a live performance of Katy Perry's song Swish Swish.
He even wore his signature rucksack on stage.
In December 2018, Russell announced that he was suing Fortnite publisher Epic Games for using his moves in-game without permission.
A representative for the company said: "We do not comment on ongoing litigation."
Why are some calling for it to be banned?
The craze, which hit new heights in Britain after Tottenham ace Dele Alli celebrated his 22nd birthday with a hilarious attempt at the dance, has led a school in Devon to ban the move.
While Kate Garraway and Charlotte Hawkins embraced their "embarrassing mum" sides on Good Morning Britain, it seems Ilfracombe Junior School is keen to ensure other mums don't follow suit.
The move, which has strong associations with the ultra-popular video game Fortnite, has been accused of being used to "surround and intimidate children" in the playground.
Headteacher Catherine Cox sent out a letter to bemused parents saying: “Fortnite is about the mass killing of other human beings and being rewarded by a dance of celebration if you are successful. One of these dances is called the Nazi dance!"
However, the ban has infuriated parents who took to social media to vent their anger, with one raging: “My daughter is eight. She doesn’t even know what Fortnite is. I find this ludicrous my child now feels this way about a dance.”
