RAP DEVIL
Song Meaning

RAP DEVIL is Machine Gun Kelly’s diss track responding to Eminem’s “Killshot,” which itself replied to MGK’s earlier shots at Eminem, making it a central chapter in their public rap beef 1 2. The song mocks Eminem’s age, his sobriety, his “corny” image, and what MGK frames as a decline in quality over his last four albums, while flipping the title of Eminem’s “Rap God” into “Rap Devil” to directly challenge his rival’s claim to rap supremacy 1 2. It also uses crude, personal boasts, including a jab referencing Eminem’s ex-wife Kim, to escalate the conflict beyond just bars about skill 2. Commentators at the time described it as an unusually effective hit that seemed to catch Eminem off guard 3.

The meaning

At its core, RAP DEVIL is a direct response record. MGK wrote it after Eminem released “Killshot,” which was itself a reply to earlier disses from MGK, and the two songs together became the defining exchange of their feud 1 2. Rather than subtext or metaphor, the song works as a point-by-point rebuttal, which is why so much of it reads like a list of grievances against Eminem’s career and public persona.

A lot of the song’s meaning sits in its title and central line. Eminem’s 2013 song “Rap God” cast him as untouchable, so when MGK raps “Fuck ‘Rap God,’ I’m the Rap Devil,” he’s explicitly rejecting that claim and repositioning himself as the threat to Eminem’s throne 1. That line functions as the thesis of the whole track: MGK isn’t just insulting Eminem, he’s trying to dethrone him.

Much of the song also targets Eminem’s image and recent work rather than his technical ability. MGK calls out Eminem’s “sweatsuits and corny hats,” jokes about his age and sobriety, and claims Eminem’s last four albums were weak, using the contrast between Eminem’s wealth and continued anger as a recurring theme (“I’m sick of you bein’ rich, and you still mad”) 2. The suggestion embedded in lines like these is that MGK sees Eminem as out of touch and reactive rather than dominant.

The song also gets personal in ways that go beyond typical diss-track sparring, most notably the boast about Eminem’s ex-wife Kim, which listeners and commentators read as a deliberate escalation meant to provoke rather than just outrap him 2. Paired with claims that Eminem tried to keep MGK off the radio and blackball him within the industry, the track paints the beef as something MGK experienced as real professional interference, not just a lyrical rivalry 2.

Taken together, RAP DEVIL functions less as an abstract meditation and more as a direct, aggressive rebuttal built for a specific moment: proving MGK could go toe-to-toe with one of rap’s most feared battle rappers and, in the eyes of many listeners, land the harder punch 3.
