When you are having a life threatening shit. It partially comes out of your anus and gets stuck because it is too big and strong to slide out easily.

The anus cannot cut through it. It will not go back inside. The only way is to power through and hope you do not blow your anus out. If you are lucky this ordeal will be over within minutes.
It won't come out, it won't go back, it's Turtle's heads! - Turtles' Heads by the Macc Lads.

When you have to take a poo ... Really bad, but don't have access to a bathroom. The poo pokes out of your butthole as you try to sqeeze it back in so you don't shit your pants. Much like the way a turtles head peeks in and out of it's shell.
Often you can tell if one is turtle heading because they will walk funny, from the effort it takes to keep from shitting their pants
Dude1: wow look that guy is walking funny!!
Dude2: hahaha yeah he's definitely turtle heading !!!
