A word derived from the
stoner-culture. It means to act stupid, or do something stupid. It also can mean to be burnt, meaning you are slow or blank, because you're zoned or high.
It is DEFINITELY regional! Me and my crew from
DC used it religiously. Once I moved to Miami (and now other parts of
Florida) people had NO CLUE what the word was. No one from down here has ever heard of it!
