Bräter
A is a slang term for lying in bed with another person and pulling the covers over the person's head while flatulating, thereby creating an unpleasant situation in an enclosed space. This is done as a prank or by accident to one's sleeping partner. The book "The Alphabet of Manliness" discusses the Dutch oven and a phenomenon it refers to as the "Dutch oven surprise", that "happens if you force it too hard". The "Illustrated Dictionary of Sex" refers to this as a Dutch treat.
