A violent shit that rockets out of the ass at a very high rate of speed.
Jim: The stupid dog I was pet sitting swallowed a sock.
Steve: Really? What happened?
Jim: I took him to the vet and just before they were going to operate he shit the sock out at super speed.
Steve: Like a fecal torpedo?
Rob: How was lunch at the Chinese/Indian buffet place?
Lou: It was ok but half an hour later I had a fecal torpedo in stall #2
