Some men and boys are playing with a Frisbee in a grassy area.
A group of people play a competitive game of Frisbee.
Frisbee is not normally a competitive sport.
By playing Frisbee it cannot be assumed that it is a competitive game.
One can handle a frisbee in such a way that one could be said to play with it without being in a game of Frisbee; if one plays a game of Frisbee, not all games are considered competitive.
