The Republic of Long Island
n. The location immediately east of continental New York. It is a fish-tail shaped island 118 miles long that nestles the eastern shore of Manhattan. Composed of 4 major counties: Nassau (Western LI) and Suffolk (Eastern LI) as well as Kings and Queens Counties which are also geographically located on the Republic of Long Island. More commonly known as simply Brooklyn and Queens (respectively), they they are often referenced as part of "The City" (as they are 2 of the 5 NY boroughs). "The Republic" terminology comes from the fact that many Long Islanders believe they are separate from the United States, and independent country, if you will, and it is a humorous spin on the idea that Long Island is so vastly different that it makes up its own country. Citizens of The Republic of Long Island are often obsessed with their upbringing, sometimes trying to act as though they are "gangsta" when they are really not, and often reference their proximity to New York City ("The City").
