This challenge is part of Fortnite Season 3 Week 10 Challenges and you'll have to dance for 10 seconds on the Apres Ski dance floor, southwest of Misty Meadows. It's not too complicated once you know the location on Apollo Island.
Map
The dance floor is located on the first floor of the building. As with all Fortnite dance floors, the floor is bright where you can complete the challenge.
During the week following the challenge, the location might become a war zone. It's unlikely that other players will give you the opportunity to perform your full dance. In that case, feel free to spawn in the back and then head to the chalet later in the game. You can also opt for the much quieter Team Rumble option.
