Song meaning of Killshot by Eminem

Oh boy, Eminem is at it again in Killshot! At first, it seems like he's just trying to roast some poor, weird-bearded rapper who dared to diss him. But then he drops a bombshell about leaving hickeys on Rihanna's neck. Wait, what?! Suddenly, it's a savage back-and-forth, with Eminem taking shots at the other guy's age, fame, and even his breakfast cereal choices. And hey, if nothing else, at least the dissing allowed Eminem to shout out some classic names like Ja and Benzino. But he ends by telling the other rapper to keep his daughter's name out of his mouth, and well, let's just say it doesn't end on a very friendly note. But hey, Diddy, don't worry, Eminem still loves you!
