The Schweizer Bakery is similar to a dutch oven. It is the act of farting in a car and then immediately stepping out and closing the door, trapping the other occupants of the vehicle in with your ass gas. This is most effective when you're stopping somewhere briefly, i.e. a store, to run in briefly while others are inclined to wait in the car.
Dave pulled into the quicky mark to buy a slurpee. His girlfriend said she would wait in the car--and he totally trapped her in the Schweizer Bakery!
