The phrase plays on the familiar, affectionate way New York City is shortened and exaggerated in casual speech, turning a simple city name into a small performance. Short voice clips like this circulate widely as reaction and intro sounds, because they are instantly recognisable even without context and easy to drop into a video. Creators use it as shorthand for excitement about the city, for travel content and for New York themed jokes, which keeps it in rotation long after any single post fades.
