What is a bumb in volley ball?

Answer 1

A bump is when you pass the ball with your forearm, often used to receive a hard serve, or a ball that is too low to pass on above your head, and is one of the basic skills to master in Volleyball. A bump is usually the first pass which goes to the setter for a hitter to hit it over. The precision of the bump is not the best, so to prepare an attack (with a spike) i.e. to "set", an overhand pass i preferred, with the fingertips.

To bump, you put your hands together, thumb to thumb, closing one fist on the other to form a "ball". Then the incoming ball is hit from below with a distinct impact, and may gain high velocity.

A bump is also called a forearm pass or just a pass, but is sometimes used as well to hit the ball to the opponents' court side, as a weak "attack".

Answer 2

A bump is when a player cups his/her hands together and passes the ball using their forearms.
