A dump pass is a short pass that occurs upfield. It is a reset throw. One common occurrence of a dump pass is when a player looks at a handler, the handler executes a butter-cut behind the player with the disc, and the disc is thrown to them.

A dump pass is a slightly altered backhand throw. The disc is held the same way as a backhand; in general, the split finger grip is the most useful because it causes the most spin to occur. Getting spin in such a short distance can be difficult, but without spin turnovers are more likely to occur.
You want to keep your arm straight out in front of your body - with a slight bend in your elbow - when throwing a dump pass. Rather than move your arm across your body from one side to another like a regular backhand throw, you want to move your arm in an upwards fashion from your waist to your shoulders. You will release the disc as your arm moves upwards in order to make it partially float. This way a handler can run onto the disc.
With your body movement, you want to face the area where the cut is going to occur. You should be able to shield your throw from the mark. For instance, if you are throwing to a handler executing a butter-cut, turn completely around to face the opposite end zone, and place your body between your defender and the disc. You want to step out away from your mark when throwing the disc.
