Wear a G on my chest, I don't need Dapper Dan
Back in the day, cats used to wear leather suits with Gucci print all over them…these were called Dapper Dan suits.
Dapper Dan has started his own Tumblr called Dapper Dan Of Harlem
This can be seen on the now classic Eric B and Rakim album, Follow the Leader.
Jay is saying that he’s a G, short for Gangsta, and that he doesn’t need a Dapper Dan suit to prove so.
Additionally, this line can be interpreted as Jay wearing a shirt, outfit, or chain that costs a G ($1000), and it not being a knockoff Dapper Dan suit.
Finally, he’s likening himself to Superman who wore an S on his chest to denote his Superhuman like powers. Jay wears his Gangsta, or G, on his chest to prove to a younger generation of Gangstas that he’s really about his and not afraid of them or anyone else. This is insinuated due to his experiences dealing with learning cop cars and earning battle scars.
