It's a very rare feature on the back. Some people believe that back dimples are genetic like, a cleft chin.

Describe the process of breathing. During inhalation the ribs move up and out as the intercostal muscles contract and the diaphragm contracts and flattens. This increases the space in the thoracic cavity and air rushes in. In exhalation the ribs move down and in as the intercostal muscles relax and the diaphragm moves up as it relaxes. This decreases the volume and so air rushes out.
