Doodle-sack, noun, is an oldish word for "bagpipe." Fair enough, I knew that. It is also a pre-1800 word for, to quote GURPS Goblins, "that part which typifies and defines the female gender."
There is a strange and sinister coincidence here which does not bear thinking about. I'm dimly reminded of the ping-pong-ball scene from Priscilla, Queen of the Desert.
