Keep Our Scene Clean. It's a campaign started by the PLURR Semi-Sober Ravers from all over. They don't mind the drugs that go on at raves, as long as the people doing the recreational activities are being responsible about it.
on myspace or plurspace you would put KOSC next to your display name to show that you like to "Keep The Scene Clean"
