Terminology (all for a right-hand player. Reverse for the left hand player.)
Hyzer
Releasing the disc with the outter edge at an angle lower than parallel to the ground. This will cause the most discs to curve to the left for a right-hand backhand player.
Anhyzer
Releasing the disc with the outter edge at an higher than parallel to the ground. This will cause the most discs to curve to the right for a right-hand backhand player.
High Speed Turn
The characteristic of a disc to curve to the right at the beginning of its flight when thrown hard.
Low Speed Fade
The natural tendency of a disc to tail left as it slows down at the end of its flight.
Overstable
A term used to describe the relative resistance to high speed turn and amount of low speed fade of a disc. A more overstable disc will generally have higher resistance to turn and greater low speed fade.
Understable
A term used to describe a disc with relatively low resistance to high speed turn and less low speed fade.
Turnover
The term used to describe the flight of a disc that curves to the right when thrown flat or at hyzer. A less overstable or understable disc will generally be easier to turn over.
Nose Down
Releasing the disc with the front end of the disc lower than the back end. Certain discs will fly better when thrown nose down.
Nose Up
Releasing the disc with the front end of the disc higher than the back end.
Stall Out
A term used to describe the flight of a disc when it peaks in height and drops off to the left without much glide. This generally occurs when the disc is thrown with the nose up.
S-Curve
A term used to describe the flight of a disc when it begins by turning to the right and then “flexes” out and glides back to the left.
Roller
A type of throw where the disc is turned over so far that it lands on its edge and rolls.
Snap
A term used to describe the armspeed and power a player gets into their throw. More snap will generally make the disc fly faster and further.
