A group of assholes from Philly who descend upon peaceful festys and shows in droves to sell their sub-par nitrous oxide. Their only concern is making money. They do not care about the music, the scene or the people. After they have raped the scene of thousands of dollars, they disperse, leaving the area littered with balloons.
can you believe the Nitrous Mafia was trying to sell balloons 3 for $20!?
