The same people who gave us "Hipster Traps" are now trying to ensnare Bridge and Tunnel people. Bait includes Hair Gel, Bronzer, Drakkar Noir and PATH Train tickets (SOURCE).
"Bridge and Tunnel" is how many Manhattanites refer to the people residing in New Jersey and/or the other boroughs of New York City. Obviously, 'B & T' refers to the ways in which these people access "The City" (AKA Manhattan). The term is especially popular when referring to nightlife (Example: "We went to Marquee for some drinks last night but it was filled with nothing but Bridge and Tunnel. We won't make that mistake again").
A perfect example of Bridge and Tunnel: Every person who has ever appeared on Jersey Shore.
