Wikipedia says: The buttocks (singular: buttock) are two rounded portions of
the anatomy, located on the posterior of the pelvic region of apes and humans,
and many other bipeds or quadrupeds, and comprise a layer of fat superimposed
on the gluteus maximus and gluteus medius muscles. Physiologically, the
buttocks enable weight to be taken off the feet while sitting. In many
cultures, they play a role in sexual attraction.[1] Many cultures have also
used them as a safe target for corporal punishment.[2] There are several
connotations of buttocks in art, fashion, culture and humor, and the English
language is replete with many popular synonyms. In humans they are located
between the lower back and the perineum.
