Definition

The intergluteal cleft (a.k.a. gluteal cleft / natal cleft / cluneal cleft / butt crack) is the posterior deep midline groove in the gluteal region. It separates the two glutes (and the buttocks) from each other and extends downwards from the third or the fourth sacral spine, deepening as it goes inferiorly.
