A pompom – also spelled pom-pon, pom-pom, or pompon – is a decorative ball or tuft of fibrous material. The term may refer to large tufts used by cheerleaders, or a small, tighter ball attached to the top of a hat, also known as a bobble or toorie.
Pom-poms may come in many colors, sizes, and varieties and are made from a wide array of materials, including wool, cotton, paper, plastic, thread, glitter, and occasionally feathers. Pom-poms are shaken by cheerleaders, pom or dance teams, and sports fans during spectator sports.
