\Ten"der*loin`\, n.
1. A strip of tender flesh on either side of the vertebral
   column under the short ribs, in beef or pork. It consists
   of the psoas muscles.
2. In New York City, the region which is the center of the
   night life of fashionable amusement, including the
   majority of the theaters, etc., centering on Broadway. The
   term orig. designates the old twenty-ninth police
   precinct, in this region, which afforded the police great
   opportunities for profit through conniving at vice and
   lawbreaking, one captain being reported to have said on
   being transferred there that whereas he had been eating
   chuck steak he would now eat tenderlion. Hence, in some
   other cities, a district largely devoted to night
   amusement, or, sometimes, to vice.
