That accent isn't a New Jersey accent per day lol. Not even people on the shore got that accent haha.
The "Jersey Shore" accent is actually a form of the Italian and New York accent. And it traveled to NJ when a bunch of Italians came to Joise.
I don't have that accent as I'm a proper young lady

I also grew up in a Spanish household so I have a tinge of a Spanish accent on certain words.
