The moment when you can't hold in youre poo and the tip of the shit comes out of your anus. Most of the time you are able to pull it back in when you have strong sphincter.

When you have to poop really bad and can't hold it,that is when you tortoise. You let the poo come out of your anus just a little bit so i looks like a tortoise coming out of it's Shell.
