Bring it back to the peekhole, that's the circle of my peers
Double Entendre Alert
You can read it like “bring it back to the people that’s the circle of my peers.” In which the people = Lupe’s peers. He’s saying that a circle of his peers is small — think the peephole (“peekhole”) on your door.
A porthole is a circular window typically found on boats (a sailboat is mentioned in previous line). Peephole = circle of my peers (looking out the window or peering)
