Turtle Tail Edit Meaning

1.

Having to take a dump so badly that the turd is starting to wiggle its way out of the gate. Incorrectly defined on slangdefine as turtle head, "turtle tail" is a much better descriptor for a tapered turd that has quietly poked its way out of your posterior.

Dude, can you pull over at that gas station? I've got a turtle tail.
