How can Jersey Shore have overlooked the Much more Prevalent and Long Standing History of Bennies (Jews from NY)  and Shoobies.(Lunch Box Philadelphians) ?? 
 

... On the Jersey Shore, the two main terms for unpleasant outsiders are bennies  and shoobies.  Roughly speaking, bennies  are those who descend from the New York area to the beach towns of Monmouth County and northern Ocean County (like Seaside Heights, where MTV shot the first season of "Jersey Shore"). Shoobies  generally come from the Philadelphia region to towns farther south, with the southern tip of Long Beach Island marking the dividing line between the realms of bennies  and shoobies. 

Shoobies  came first, historically, thanks to the convenient train lines that have run from Philadelphia to Atlantic City since the late 19th century. As John T. Cunningham explained in his 1958 book, "The New Jersey Shore," day-trippers from Philly took advantage of the $1 round-trip fare to make excursions to the shore, especially on Sundays. "That day", Cunningham wrote, "week in and week out, found swaying Atlantic City-bound coaches teeming with Philadelphia families, laden with their ?shoe box lunches.?" 

Those lunches packed in shoe boxes were so associated with the influx of Philadelphia visitors that they likely gave rise to the term shoobie. 

Bennie  or benny,  though a newer word, is shrouded in greater mystery. The first print appearance documented by the Dictionary of American Regional English is in an unpublished paper by Robert A. Foster, ...wrote that bennie  refers to "tourists from New York City and North Jersey," and speculated that it comes from the Jewish name Benny, used as a label for Jews in general, "well-known in working-class New York City."....
