Ass Crack

Ass crack is a slang term used to refer to the cleavage or exposed area between the buttocks.

This phrase is often used informally to describe the visible gap or crevice when the pants or underwear of an individual slip down or are pulled down, revealing the area between their buttocks.

Example 1: “When John bent over to tie his shoelaces, his pants slipped down, exposing his ass crack.”
Example 2: “Emma couldn’t help but giggle when her friend’s underwear peeked out from her jeans, revealing a bit of ass crack.”
