Bump
A pass (aka bump, forearm pass, underhand move) is used in volleyball on almost every play. When someone serves it and it is about at your stomach, you want to pass, to lift the ball. If a ball is at your face, you can set without a pass. If it's in the middle, step back to make a pass. You pass on a hit, too.
all bones are used in some way, shape, or form.

Volleyballs have to bounce in order for them to be used in volleyball. What would happen if a volleyball didn't bounce on a forearm pass? Think about it.
