Someone whose butt is so used it’s like a pizza with eight slices and tentacle toys hanging out like spaghetti

My teacher is an octobussy. She has eight holes and a banana in one.

My brother's butt looks like a monster’s cave. Octobussy for sure.

My neighbor's butt is so big it's like a monster. Tentacles everywhere.
