Alright majority of these posts are used for a rivalry between Darien CT, or another nearby town. D-Bagers are kids from Darien, usually D-Bag is used as an insult calling teens rich preppy kids who are fairly snobby. In truth D-Bagger can be used to describe both the person insulting and the person being insulted. Dariens preppy, New Cannan is preppy, Norwalk not so much, Wilton is preppy, and Greenwich is preppy too get used to it.
P.S Im from Darien and i know both sides of this argument.
John:Hey Jerry look at those D-bagers, im so happy to be from New Cannan.
Jerry: Shut up and get in the porche.
