I don't think he directed it at anyone in particular... but that verse definitely says fuck all off these wack emcee's before me, im the best on this track. He even says I'm a kill you before you think of responding and saving face. Eminem most definitely shitted all over the other emcee's on this track. Drake you are not the greatest ever, and you lose points in my book for even suggesting that. Get The Fuck Outta Here
Not sure if this is really Nick Cannon, but its a wack attempt at dissing Eminem, should of dropped more verses, not just one minute... again if it is Nick, this is not who you defend your wife
