Unlike the Aerobie, flying discs are used in both Ultimate Frisbee and Disc Golf. The Frisbee brand of flying disc is rarely used in official competition in either game, which is why the team sport of Ultimate Frisbee is officially called simply "Ultimate." Still, as "Kleenex" was once a word used to mean "facial tissue," "Frisbee" is still broadly used as a synonym for a flying disc.
