I haven't really watch that show. I saw a few clips of it and part of an episode, enough to get an idea.
Pretty much everyone I know makes fun of Jersey Shore and anyone from new Jersey trend to distance themselves.
I was once in New York was at the early morning (or end of the night for them) ferry back to Staten Island. Apparently, they were heading back home after a night of clubbing. My friend with me was worried and scared as they were drunk and unruly. I was more amused and saw that they have that "hey bro" type of mode going on.
In person and in the show, they definitely have that douchebag quality.
However, the305 is correct. They possess the DJ quality of confidence, fun in the moment, around lots of women, in-shape, groomed, and a don't care (relaxed) mentality. I don't know about being passionate, didn't get to see that, though I can imagine that.
On the other hand, I can the dissenters point of view since my personality leans from that camp. It is not hating for their ability to get laid and laid well, but their personality.
They definitely have this vapidness about them. A large lack of self-awareness spending nights drinking and partying. Bluntly, they sound dumb. Both the women and the men, but there's no denying the women are hot.
I think part of the dissenters issue is if praising them without thought means that if we are to be true DJs, we have to act like them, including losing the sense of introspection, consciousness, and intelligence with a touch of trashiness and lack of class or perhaps the truth is they actually want that part instead of what 305 listed.
