The way in which everyone not from Long Island insists Long Islanders pronounce "Long Island", regardless of how they actually pronounce it.
"Where are you from?"
"BAHAHAHAHA, you just said Lawn Guyland ! And I'm not just saying so because I heard somewhere that people from Long Island do that."
The way people from Long Island, New York say the name of their hometown.

The supposed way that all Long Islanders pronouce the name "Long Island."

guy from North Jersey: shut the fuck up, man!
