A 'Bush Doof'' is an event where hippies and just down right cook heads head into a random bush and listen to non stop trance for days on end. Copious amounts of drugs are consumed and people essentially doof in the bush. For something to be defined as a bush doof 50 or more people have to be present listening to doof music together while the sun rises.
Hey John how sick was that party in the bush last night, I didnt know any of those trance songs.
John: Thats what I call a bush doof Johnny.
