Pittsburgh is a city in Western Pennsylvania, United States, and the county seat of Allegheny County. Until the later part of the 20th century, it was a major industrial city, a mainstay of the American economy.
Reggie Pesky was from Pittsburgh. Occasionally he would lapse into Pittsburgh slang, such as saying "yunz" for "you all." He explained to Jefferson Governor Bill Williamson that people who spoke like this were called "yunzers."
