MOOP
n.— «We want to hand out plastic mugs w/ our camp location on them as an invitation for people to come back to drink tea w/ us and hang out. Much better than flyers which are likely to end up as MOOP (Matter Out Of Place) which is an important consideration in a Leave No Trace environment.» —“Tearing the house apart” by Tamara (tmonsta) LiveJournal for Tamara (Portland, Oregon) Aug. 8, 2003.
