In Roller Derby, a jam is the two minute time period in which both teams try to score points against the opposing team by circling the trackin packs and moving their jammer past the opposing blockers. The jammer scores a point each time her hips pass an opposing blocker. The lead jammer can call off the jam by repeatedly putting her hands on her hips.
The lead jammer scored 12 points before she called off the jam.
