Punk Aesthetic
Primarily in the U.S., a punk aesthetic and third-wave feminist ethic is prominent among roller derby players. In 2009, the feature film Whip It was based on roller derby, introducing viewers to its rules and unique punk culture.
Gameplay
Roller derby consists of a series of short scrimmages, or jams, in which both teams designate a jammer with a star on their helmet and four blockers who skate counterclockwise around the track. The opposing team attempts to stop the opposing jammer while assisting their own jammer, essentially playing both defense and offense at the same time.
