Popping as an umbrella term also includes gliding. Gliding is a lower body dance performed with little to no movements in the chest or arms. In gliding a dancer appears as if they are drifting across the floor on ice. Opposite from gliding is tutting, an upper body dance that uses the arms, hands, and wrists to form right angles and create geometric box-like shapes. Tutting can be done primarily with the fingers rather than the arms. This method is called finger tutting. In both variations the movements are intricate, linear, and form 90° or 45° angles. In practice, tutting looks like the characters on the art of ancient Egypt, hence the name—a reference to King Tut.
