Love hurts—literally!—as the OC Roller Girls hit the track in a fast-paced, girl-on-girl jam where players arrive protected by helmets, elbow pads, wrist guards, knee guards—but not much else. Watch as the teams’ competitive jammers hip-bump and booty-push their way through packs of bloodthirsty derby girls, with both offense and defense sashaying around track simultaneously. In this next cutthroat competition, the Huntington Heartbreakers take on the Back Bay Bombshells. Remember: all you need is love!
