In roller derby, the person who has always got your back, no matter what, is your "derby wife." Rollygamy is the practice of having multiple derby wives. (credit to Bat Wing of the STL Gatekeepers)

Roxy Horror participates in Rollygamy, as she is married to Maim-y Fisher, Momma Knee Ya, Fice-T AND Bat Wing.
