Turtlehead poking out 

When you really need to poop and are in the car, opening your front door, etc. and you feel as if the turd is beginning to force its way out. This may actually be happening or just a sign that it will if you don't get to the toilet fast enough.

"Mom, please hurry up!"
"I'm at the speed limit, Fred! What could be so important that you would risk casualties?"
"Please, I've got a turtlehead poking out, Mom!"
"Urgh, Fred..."

Turtle head poking out can mean two things:

1) To have an extreme urge to defecate, so much so that the feces is already spreading the anus and a portion of it is beginning to stick out. So called because it resembles a turtle poking its head out of its shell.

2) The portion of a long log of shit that protrudes above the water in a toilet. Since it is above the water, it can be smelled. So called because it resembles a turtle poking its head out of the water.

1) May I use your bathroom? It's urgent, I have a turtle head poking out.

2) You may not want to go into the washroom for a while: I just had a crap and there was a turtle head poking out; the smell is awful.
