A fart that produces a surprisingly loud noise due to the plastic chair being sat on acting as an amplifier.
John was sitting in the Doctor's waiting room when he felt the need to fart. He tried to slip out a silent one but ended up doing a plastic fart. It was so loud an old lady shit herself and two babies started to cry.
