My shit is butter for the bread, they wanna toast me
A carb-based metaphor: “Butter”; is slang for crack, hustlers call it butter because of the way it melts. Must keep in mind that this song has nothing to do with rapping, it is only a hustlers anthem. “Bread”; means money, and his competitors want to “toast”(shoot) him.
The verse is actually used as a double entendre (having two meanings in one). There is the surface content which is correctly defined, but he is also suggesting that his persona/style/being is “butter, spelled butta” -meaning cool, good, best, refined; since bread in this verse is referring to money, and toast to shoot; Jay is saying that my life if so good, for the right price people want to kill him.
