Eminem toyed with not responding to Machine Gun Kelly, who smacked Shady with the surprisingly good diss track "Rap Devil" after feeling some Kamikaze heat.

Em's reason for maybe staying silent is that he didn't want to make Machine Gun Kelly any more famous. But he ultimately decided to hit MGK back with an entire diss track, "Killshot." 

"Killshot" features the type of deft wordplay Eminem's been famous for forever. (And a joke about Diddy killing 2Pac) But is it an effective diss? Here's what Twitter is saying:

Don’t act like you didn’t know this would happen 🤭oh my what have you got yourself into. 🤨get the strap #lecheminduroi @Eminem 🐐 pic.twitter.com/LAfPiZ5UdG

Know what this generation of rap ‘fans’ are gonna say?? “Eminem’s diss is so bad! It’s not even a good song!” 🤦🏻‍♂️ y’all missing the point of a diss record..it’s not supposed to be a catchy pop hit. Fucking idiots. #KILLSHOT

If y'all want Eminem to come out with a better diss, then offer the man a better opponent. Why would you use a flamethrower to kill a roach? #KILLSHOT

If you think Trumps election has led to race relations in America getting worse then you don't want to see what happens if Jay Electronica drops a diss record to Eminem.
