So I travel with the barrel, with the chrome, with the lead
Cause when it's on, then it's on, the shots flown through your head

from Diddy (Ft. Jay Z & The Notorious B.I.G.) – Young G's Lyrics on Rap Genius

Meaning

In the words of Shawn Carter — “This might seem redundant—each of these, the barrel, the chrome, and the lead, is talking about the same thing—but breaking them down into their components allows the image to build in the listener’s mind, like the aw shit scene in every action movie where the hero assembles his gun, locks, and loads.”

Shots flown through your melon, wait!
