The player holding the disc establishes a pivot point (i.e. they cannot run with the disc, just step out from a single point). They have up to three steps to slow down after catching a disc, without changing direction, to establish that pivot point. A violation of this is called a "travel". The disc is advanced by throwing it to teammates. If a pass is incomplete, it is a "turnover" and the opposing team immediately gains possession, playing to score in the opposite direction. Passes are incomplete if they are caught by a defender, touch the ground (meaning defenders need only knock the disc out of the air to gain possession), or touch an out-of-bounds object (including the ground, or an out-of-bounds player). Once possession of the disc is obtained, however, it cannot be forced out of the throwers possession before it leaves their hand. A common infraction of this nature is called a "strip", in which one player feels that they had enough possession of the disc to stop its rotation before it was taken out of their hand. However, if a player jumps from in bounds, catches, and then throws the disc while in the air and technically out of bounds, the disc is still in play and can be caught or defended by players on the field. This feat of athleticism and precision is highly praised, and dubbed "Greatest."
