they used to play at my grandmother's house when I was a kid. The two men are just playing, showing each other tricks and fooling around with the fire. It was supposed to show one is a clown and other is not. It makes more sense if you grew up hearing the beats of the song, and the singing it evokes a lot of emotions in you. I love it. I hope this helps. I am from the same tribe as them, Fula, we call ourselves Peulo Futa, all the other varians of the name are European inventions.
