Pineapple Butt 

After taking a large poop, the act of not wiping and allowing the poop to dry and get crusty, followed by the sensation of having the top of a pineapple in your asshole is known as pineapple butt.

Man, Chipotle was out of toilet paper. When I got home, I had a bad case of pineapple butt

I started to bleed from wiping but still had shit to remove. Two hours later, I had wicked Pineapple Butt.

When you put two hands, palms together, in someones asshole and wiggle your fingers back and forth interlocking. It looks like a pineapple.

Penelope thought Harold deserved a butt pineapple last night. It was a good way to shut him up
