bump ball (plural bump balls)
- (cricket) A ball that bounces off of the pitch immediately after being hit by the bat, and goes up in the air.
2005, David Fraser, Cricket and the Law: The Man in White is Always Right, →ISBN, page 302:
- The umpire believed, mistakenly, that it was a bump ball and Boucher was allowed to remain at the crease.
- Often used in the context of possible catches, where it is ambiguous whether the ball has been hit into the ground (not out) or into the air (out).
