Park Avenuer (wealthy/snobby person who lives on Park Avenue)

A person who lives on Park Avenue—a street known for its wealthy residences—is a “Park Avenuer” or “Park Avenoor.”
     
The term “Park Avenoor” was popularized by Joseph Van Raalte, who wrote a syndicated “Bo Broadway” newspaper column. “Then there’s the Park avenoor who has made friends, unwittingly, with a ‘con lady,’” Van Raalte wrote in the New York (NY) World in February 1922.
 
“Park avenuers” was printed in a 1927 newspaper and “Park Avenuers and Fifth Avenuers” was printed in a 1927 book. The “Park Avenuer” term also sometimes means “rich snob.” However, “Park Avenuer” became less popular after the 1920s and 1930s.
   
   
Wikipedia: Park Avenue
Park Avenue is a wide New York City boulevard[4] which carries north and southbound traffic in the borough of Manhattan. For most of the road’s length in Manhattan, it runs parallel to Madison Avenue to the west and Lexington Avenue to the east. Park Avenue’s entire length was formerly called Fourth Avenue; the title still applies to the section between the Bowery and 14th Street.[5] Meanwhile, the section between 14th and 17th Street is called Union Square East, and between 17th and 32nd Streets, the name Park Avenue South is used.
