Dutch coven
This is a situation that occurs when there are at least five, consensual humans engage lung in the act of group sharing flatulance. At least one of the five participants must expel gas under a material (I.e. sheet,bedspread, tarp, etc.) and the remainder of said participants all cover their heads and breath through their noses.
Bob and Linda really loved running a hot dutch coven with the other HOA committee members every Thursday after the neighbor book club meeting.
