All-female, grassroots leagues
Nearly all contemporary roller derby leagues are all-female and self-organized, and were formed in an indie, DIY spirit by relatively new roller derby enthusiasts. These leagues deploy traditional quad roller skates, and a punk aesthetic and/or ethic is often prominent. Many, if not most, are legally incorporated as limited liability companies, and a few are non-profit organizations. Most compete on flat tracks.
Each league typically features two or more local teams which compete in public matches, called bouts, for a diverse fan base. Members of fledgling leagues often practice and strategize together, regardless of team affiliation, between bouts. Moreover, as the business and infrastructure of the sport matures, successful local leagues form travel teams to compete with the roller derby leagues of other cities and regions.
Most players in these leagues skate under aliases, many of which are creative examples of word play with satirical, mock-violent or sexual puns, alliteration, and allusions to pop culture. Examples include Sandra Day O'Clobber (Sandra Day O'Connor), Scariett Tubman (Harriett Tubman), Skid'n Nancy (Sid Vicious and Nancy Spungen), Goldie Knoxx (Goldilocks, Fort Knox), and Anna Mosity (animosity). Some players claim their names represent alter egos which they adopt whilst skating.[citation needed] By the 2009 season, however, a small number of players on at least three leagues had started skating under their real names.
The names of the bouts themselves are typically as sardonic and convoluted — for example, Nightmare on Hull Street (Nightmare on Elm St.), Seasons Beatings, (Seasons Greetings), Night of the Rolling Dead (Night of the Living Dead); Spanksgiving (Thanksgiving), Grandma Got Run Over By a Rollergirl (Grandma Got Run Over by a Reindeer), Skate & Destroy Her, Cupid's Quarrel, Shamrock and Roll, Pushin' Daisies, Cinco de May-hem (Cinco de Mayo), and War of the Wheels (War of the Worlds).
