There's a Native American lake named Chargoggagoggmanchauggagoggchaubunagungamaugg. It means "you fish on your side, I fish on my side, and no one fishes in the middle."

Located in the town of Webster, Massachusetts, it is known more commonly as Lake Chaubunagungamaug or Webster Lake. Its full name comes from Nipmuc, an Algonquian language, and when translated directly means “Fishing Place at the Boundaries -- Neutral Meeting Grounds.” 

Its name is often cited as the longest name of a location in the United States. Though most commonly known as Webster Lake, many area residents consider the longest version of the name to be correct (according to the US Department of the Interior). 

There have been numerous other translations, though all of them have been generally similar. Other translations have included “boundary fishing place,” “fishing place at the boundary,” or “that which is a divided island lake.”
