Hedgehogs Head
In your quest to find a toilet urgently, your poo might poke its head out like a hedgehog. At this point you must clench your cheeks to shove it back inside. It may then continuously pop its head out at ever increasing regularity. At this point you really should be near a loo.
Oh I really need a loo. I've got a hedgehogs head.
