While Eminem was on tour in Australia, the crowd at a recent Brisbane show demanded a performance of the Machine Gun Kelly diss track, “Killshot.” Rather than oblige, Em called MGK a “cocksucker” and moved on with his set.

MGK evidently caught wind of Slim Shady’s sentiments and retaliated on Twitter.

“ay @Eminem u made the right decision not dropping that weak ass song in concert and putting everyone to sleep,” he tweeted. “#RapDevil.” His tweet also included a series of emojis, including a thumbs down and a person throwing something in a trash bin.

Released last September, “Killshot” served as a response to MGK’s Slim Shady diss, “Rap Devil.” The track marked YouTube’s biggest Hip Hop video debut in the platform’s history and sparked a community-wide debate over who won the battle.

Redman, who was at HipHopDX headquarters earlier this month, weighed in on the debate and gave props to both participants, but took issue with one particular line.

“MGK, you did a great job on that fuckin’ battle, but there’s one thing you never fuckin’ do,” he said. “One thing. And that’s talkin’ about a man’s sweatpants. You can talk about his mama, but you do not talk about a man’s sweatsuit.”
