A small nub filled with blood clots protruding from the anus.; aka, piles, a hemorrhoid. Ass on fire. Spicy Butthole McNuggets may require surgery.
My girlfriend, a vegetarian, was tossing my salad when she screamed after tasking my Butthole McNugget.

After eating at McDonald's 27 straight days, my turds turned to stone and I had to strain so hard that Butthole McNuggets grew on my anus.
