Young teenager or pre-teen who has mistaken Ultimate Frisbee as a sport, and as a result won't stop talking about it or playing it with their idiot friends. The normal frisbeekid is usually quite un-athletic and has a tendency to unnecessarily wear an extreme amount of overpriced under armor. Frisbeekids grow most easily in Suburban areas, and will frequently talk about their love of the outdoors.

Note: The Frisbeekid is not to be confused with the bro.
