protestival
n.— «Somewhere around 300,000 people converged on the Seattle waterfront Saturday and Sunday to attend the 19th annual Seattle Hempfest, the world’s largest marijuana “protestival,” as organizers like to call it. While organizers and drug reform advocates were out in force to encourage attendees to get involved in changing the marijuana laws, for most of the crowd, Hempfest was one big pot party.» —“Seattle Hempfest Bigger Than Ever in 2009, But Gaining Critics” Drug War Chronicle Aug. 21, 2009.
