Peasant like a peacock, hesitant like heroine
A peacock is a symbol of grandeur or royalty. Heroine makes you really drowsy and can cause hesitance. So P.O.S. is saying that he’s not a normal, every day peasant or person. And he’s not hesitant at all, which the next line implies.
This whole line means he’s actually the opposite of a peasant and heroine.
