tenderloin

A tenderloin, of course, is a juicy and tasty cut of meat. In the late 19th century, however, Tenderloin saw use as a nickname for the neighborhood of midtown Manhattan, west of Broadway and below 42nd Street. This district, which contained numerous bordellos, gambling houses, and watering holes, alongside theaters and hotels, became a hotbed of corruption - and, it was alleged by some, blackmail by police. The notion of dishonest law enforcers being able to afford a nice meal off activity in this district is believed to have given the Tenderloin its name. Soon the term was applied to similarly seedy districts in other cities.
