The other day, Kendrick Lamar took his guest verse on Big Sean’s “Control” as an opportunity to casually invite all his friends to fight to the death: “I’m usually homeboys with the same n***as I’m rhymin’ with / But this is hip-hop and them n***as should know what time it is / And that goes for Jermaine Cole, Big KRIT, Wale / Pusha T, Meek Millz, A$AP Rocky, Drake / Big Sean, Jay Electron’, Tyler, Mac Miller / I got love for you all but I’m tryna murder you n***as / Tryna make sure your core fans never heard of you n***as / They dont wanna hear not one more noun or verb from you n***as . . .”

Benzino made things even worse for himself when he attacked Eminem on dubious racial grounds. Em came down on him like a combat boot on an ant with “Nail in the Coffin” and “The Sauce,” where he chuckled while imagining Benzino being held out of a window. The beef continued for a while after that, but in the end Benzino was a total laughingstock and Eminem was still Eminem.
