Bodyparts named Elvis

• The pelvis is the bony structure located at the base of the spine (properly known as the caudal end). The pelvis incorporates the socket portion of the hip joint for each leg (in bipeds) or hind leg (in quadrupeds). It forms the lower limb (or hind-limb) girdle of the skeleton.[link]
• The King was soon nicknamed Elvis the Pelvis because of his sexually suggestive performance style.
