MOOP

MOOP is an acronym for “Matter Out of Place”, a convenient way of referring to anything that is not originally of the land on which our event takes place. So everything that wasn’t originally on or of the Black Rock Desert, no matter how small, is considered MOOP, and is to be removed as part of our Leave No Trace efforts. MOOP also includes greywater, and the particulates contained therein.

“Matter Out of Place” isn't in this space, because we call it a bad word: MOOP.
