new jack 

an individual whos new to a scene who may or may not really be into it, as in they may or may not be a poseur but are still ridiculed for being a late comer.
a new jack can also be some one who all of a sudden became "interested" in a scene and the next day dress as best they can to fit into the scene.

that new jack thinks she can fit in if she dresses like us, i dont even think she listened to punk until yesterday.
