When one has to have a bowel movement so bad that the head of the turd starts to come out. The owner may be able to suck it back in for awhile longer, but if a restroom isn't found, the turtle turd will rear it's ugly head again.
A Turtle Turd can be compared to when a turtle pushes its head out of its shell, only to find danger on the outside world and quickly pulls its head back in its shell.
