Mark!

"Mark!" is shouted at the beginning of each round of bocce ball by the players to the spotter. The spotter's job to point out the location of the jack (the official name of the small, white target ball). This becomes very important in rounds where it is often difficult or even impossible to see the jack from the throwing line. Examples of when you need a mark include: a long-range game, a water game, or a dune game. The spotter will point to the jack, giving the player an accurate idea of how to adjust his or her shot for the given round.

While it is completely unnecessary in the extreme short game, many players still asked the spotter for a mark for the sake of tradition.
