Freebase (0.00 / 0 votes) Rate this definition: Bowling. Bowling refers to a series of sports or leisure activities in which a player rolls or throws a bowling ball. In indoor bowling, the target is usually to knock over pins. In outdoor variations, the aim is usually to get the ball as close to a target ball as possible.
Bowling balls are made out of polyurethane, plastic, resin and a thick outer coating that allows the balls to roll smoothly. These materials are combined and are used for different reasons depending on the bowling ball. In the past, bowling balls were made exclusively of heavyweight rubber. These balls were extremely bouncy and did not have much accuracy when rolling down a bowling lane. They were also not heavy enough to effectively knock down all of the pins in a game of bowling.
