Johnny pump 

New York City fire hydrants were first installed in 1808, and by 1817 flip lid-style hydrants began to appear on street corners. The term "johnny pump" is a nickname for fire hydrants that originated in Lower Manhattan and Brooklyn vernacular.

johnny pump 

Johnny pump is used throughout New York City's five boroughs as a nickname for a fire hydrant in the traditional style. Siamese and more modern pipe-style hydrants are not Johnny pumps.
This term was used commonly in The Bronx and Manhattan during the 1976 Bicentennial when they were painted red, white and blue - with stars and stripes.

Children and inner-city residents use this term more than adults or Manhattan residents not originally from the inner city.

Hey, Mikey, open up the Johnny pump so we can cool off! Your father got the crow bar?
Yo, VIto, who painted this Johnny pump with the freakin' homo flag on it? You?
