Specifically
Northern New Jersey messy.
Another way of saying: “It probably mob related without actually saying: “it’s mob related”.
An example would be noticing all of the pizza boxes in
Northern New Jersey are exactly the same no matter where you buy pizza; and, being stupid enough to ask the question “why” aloud to the owner of a random shop.
If the owner doesn’t know you as a regular customer the more common answer would be:
“Who fuckin’ wants to know?”.
But, if you are known and liked as a regular customer the shop owner will mutter:
“It’s
New Jersey messy”
meaning it’s mob related; and, that you just asked a stupid question.
