I've been following JoJo's Bizarre Adventure anime this season, it has 39 episodes total. It's currently on episode 11 (as of December 14, 2018).
I am confused with the dance that Narancia did with Fugo and Mista, while torturing Zucchero's head that got separated from his own body but was still alive, thanks to Bucciarati's Stand: Sticky Fingers.
What's the purpose of that dance and music towards Zucchero? When I listened to the music, it sounds like it's not a Japanese song, I didn't know what language they used. Does the dance have references from some sort of real life dance? Or is it just an original dance? Here is the scene when Zucchero gets tortured.
