This muscle is actually closer to the middle hump of your ass, right in the middle by the crack. It assists in the rotation of the hip (abduction of and medial rotation), and it tilts the pelvis while walking. It's attached at the top of the femur.

Well, maybe I could use more technical terms than ass and crack and not get downvoted, but why? We all know what these mean. Would butt be preferable?
