Flying disc
Flying discs are used in two popular sports, Ultimate Frisbee and Disc Golf. The Frisbee brand of flying disc is not commonly used in official competitions for these sports. In fact, the team sport of Ultimate Frisbee is officially known as "Ultimate." However, the term "Frisbee" is still widely used to refer to any flying disc, just like "Kleenex" was once used to mean "facial tissue."
