josh-a-dome means in slang: The basement of Clinton Hall houses a small and darkly cluttered locker room. Under ground fights are held every Saturday in this “dome”. A josh-adome fight can provide a mature resolution to an argument between two or more persons, or it can simply be a fight that is akin to a cockfight where everyone bets on who wins. All contact is permitted. All the fightants are allowed to kick, punch and ****. While a fight takes place, spectators can throw pillows, chair cushions, shoes and wet paper towers at the competitors. A player must pin his opponent and make them say, “I’m your *****” to win the match. “. (in Slang Dictionary, added by Sophie Bell)
