Definitions
American informal slang for the gluteal cleft — the vertical crease between the two buttocks. It's a universal, deeply unsexy term that appears in complaints about low-rise jeans, plumbing jokes, and any situation where someone's backside is more visible than intended. Buttcrack is one of those words that exists primarily to make people groan or giggle, and it does its job faithfully every time.
His jeans sat so low that every time he bent down to pick something up, the entire store got an eyeful of buttcrack.
