Really that's how you choose to come at someone as lyrically and with the wordplay of Pusha? Wayne has been done for a while but he never had enough to mess with rappers like Pusha. Clipse had some issues with him before too, I think it was over lines/swag.
I like rap beef there have been some great tracks from it. How can you not like Ether, Real Mother****ing G's, No Vaseline, I Can See the ***** In You, Who Shot ya, Hit em up
