Can't figure out if I came up w/ this
 

Or if I heard it somewhere but it's sort of like

Full metal jackets in the chamber
Metal head bullets head bangin' to St. Anger

Obviously that's not exactly how I would use it if I used it exactly but you get the gist. I feel like it might be something I heard though. Sounds like Jay-Z in my head. IDK.

Just put a twist to it to be on the safe side....good to see u though fam...how u been?
