You know you're from NJ if:

You know what a "jug handle" is.
You know that WaWa is a convenience store.
You know that the state isn't all farmland.
You know that there are no "beaches" in New Jersey - there's "The Shore".
And you don't go "to the shore" - you go "down the Shore". And when you are
   there, you're not "at the shore" - you are "down the Shore".
Even your school cafeteria made good Italian subs. And it's a Sub, not

You know how to properly negotiate a Circle.

  Wildwood. It can be no other way.
You were not raised in New Jersey. You were raised in either North Jersey,
