Dibs (also Bags, Bagsy an other variants) is a common informal convention used primarily in Canada, Ireland, the U.S., and the U.K., and by friends or siblings to reserve or declare full or partial ownership of a community resource, such as a chair. Claiming Dibs on the front seat of a car is called "Calling shotgun." In the non-English speaking world, there are some local equivalents to this term, including prems in France and pido in Mexico.
