But girl, your body's banging, jump me in, dang, bang-bang
This girl has a “banging” body, so he would like to get with her and “bang” her. And in order to join a gang, you must get “jumped in” or beat-up by the gang before joining. The “bang bang” ad-lib at the end is also a reference to Chief Keef’s catchphrase, continuing the subtle disses/allusions.
This line further echoes his past work, as he also says “bang bang” like Snoop Dogg did in Bitch Please 2, on the Marshall Mathers LP.
