Buttocks

The buttocks are two round parts of the lower body. They are on the back of the pelvic area and give padding when people sit. Buttocks are formed mainly from two large muscles on each side. These are the gluteus maximus and the gluteus medius. They go from the hip to the top of the leg, so they are not there just for decoration. The role of the buttocks in sitting and in sexual arousal are secondary functions in our species.Hennig, Jean-Luc 1995. The rear view: A brief and elegant history of bottoms through the ages. London: Souvenir.  In some African populations, the buttocks look bigger because of extra fat. This condition is known as steatopygia. It is an inherited condition first noticed in the Khoisan (San people) of southern Africa and the pygmies of central Africa. Now it has been recognised in the people of the Andaman islands in the Indian Ocean.

Slang words for the butt include booty, buttocks, bum, butt-cheeks,
