I got a voodoo doll every time I pen a verse
Not only do they say they feel it but say it hurts
No pain, no gain, nigga

from Pusha T – My God Lyrics on Rap Genius

Meaning

Voodoo dolls are said to give the creator control over the person the doll represents. Pusha’s verses share the same power as voodoo dolls and allow Pusha to make his listeners feel his music and make it hurt. If one were to not feel this pain, they would still be listening to the same corny ass raps

Also, its a play on the word “pen” as voodoo dolls are stuck with pins.
