Stay armed like a bicep, but goons are my muscle
Armed is a play on words: he stays armed with firearms and the bicep is a muscle in the arms.
In a second, related play on words muscle (like the bicep) also refers to his power/influence in the hood. Specifically he has a lot of goons that follow his orders.
Not only that, but people often refer to their biceps as guns.
“Y'all buy tickets to the gun show?”
