Wanna talk the talk? Here's your roller derby cheat sheet.

Bout - The game, as in, THE GAME. Some sports have a match, derby has a bout. Mad Rollin' Dolls home games feature two bouts; all four home teams play each other each month.

Periods - A bout consists of two twenty-minute periods. Two teams play each bout, with one match-up playing the first and third periods and the other playing the second and fourth.

Jams - Each episode of play. Jams run for up to two minutes, but can be called off sooner by the Lead Jammer.

Positions - As in any sport, derby skaters have specialized positions:

Jammer - She is the team's scorer; each team has one jammer on the track at a time, identified by the star on her helmet. The jammer is typically fast, elusive, and hard to knock down.

Blocker - Like an offensive lineman - except smaller, cuter, and much better smelling - a blocker's job is to open holes in the pack for their jammer to skate through, while obstructing the path and closing holes in the pack for the opposing jammer.

Pivot - The pivot controls the pack and her players. She skates at the front of the pack, setting the pace and positioning herself to help her jammer break through that last block, while trying to make sure the opposing jammer isn't able to get by.

Play - Pivots battle at the front of the pack, while blockers mix it up just behind them. The first jammer to fight their way through the pack legally becomes the Lead Jammer, giving her the option of “calling the jam” (ending it) when it helps her team. The jammers work to lap the pack as many times as possible, scoring points for each member of the opposing team she passes legally. They score an additional point for lapping the opposing jammer.

Penalizing - Flat-track roller derby has a vast array of personal fouls, resulting in penalties that include being subject to time in the penalty cage or humiliating activities dictated by our very own Zsa Zsa LaGore, Doll of Discipline.
