A condition of the anus. Turdilation occurs after snapping a deuce so big that the size of it and brute force of it leaving the sphincter results in a dilated rectal orifice. Dilation size and period of time of dilation will vary depending on size of the loaf. In time, the bunghole will snap back shut. Post dump anal leakage may occur while dilated.
Harvey was so constipated from eating excessive amounts of cheese that he hadn't shit in 8 days. He finally was able to cut a turd but it was so big and compacted that he suffered Turdilation after dropping it in the stool. He was 3 cm dilated for about 30 minutes afterward.
