Okay, so you know how when you hear really cool music, you might start dancing or moving your body in fun ways? Well, people who like a type of music called rap sometimes squat down low to the ground and move their arms and shoulders in a cool way to the beat of the music. This is called a "rap squat." It makes them feel like they are part of the music and they can express themselves in their own way. It's a fun thing to do to enjoy the music!
