Pom-Pon

A pom-pon is, at its most basic level, a decorative ball of fluff. Pom-pons may come in many colors, sizes and varieties and are made from a wide array of materials, including fabric, paper, plastic, or occasionally feathers. While not necessarily the most common usage of a pom-pon, the most noticeable and widely-recognized use is generally in Cheerleading and often by fans during other spectator sports.
Pom-pon is originally a term derived from the French word "pompon" and sometimes hyphenated (though possibly erroneously) in imitation of the echoic word "pom-pom". "Pompon" refers to ornamental spheres of fabric, feathers, etc., and, by extension, to a kind of chrysanthemum characterized by small, spherical flowers. This term is often spelled "pom-pon", "pom-pom", or "pompom" (see Variations below).[1] It can also refer to a pomeranian dog.
In English, there is also the synonym toorie, more used for clothes.
