Benny (n.) Bennies, pl.
1.) One who does not pay proper respect to the indigenous peoples of the Jersey shore. A colonizer.
2.) Groups of individuals who visit the Jersey shore in the summer who a.) clog the streets with beach traffic b.) rock socks with sandals c.) wear white tank undershirts displaying outgrowths of chest hair and/or track suits.
3.) A slang term for tourists of Italian-American descent who vacation in the shore towns of Belmar, Spring Lake, Point Pleasant and Manasquan.
The term derives from Bayonne, Elizabeth, Newark, and New York, though I understand the New York part specifically targets Staten Island.
Take a look at some recent controversy surrounding the uprising.
