I followed 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 Buccelati's Stand: Sticky Finger.
What's the purpose of that dance and music towards Zucchero? When I tried to hear 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 real life dance? Or is it just an original dance? Here is the scene when Zucchero got tortured.
