- (slang) Long Island in New York.
In the late 1980s and early 1990s, the "Strong Island Boys" were a mostly white, middle class "gang" or "posse" which tried to emulate the mostly minority gangs they saw in New York City.
The "Strong Island Sound", an American Basketball Association expansion team, uses Strong Island as part of its name. Its name is a play on the Long Island Sound.
While the exact date of the coinage is unknown, there are several claimants in the 1980's it was coined as a hip hop music term for Long Island. From Newsday: "To boost local black pride, Chuck D and the other WBAU DJs dubbed the Island Strong Island and gave special names to the emerging hip-hop strongholds."
