But, to make the line work in the song, he had to pronounce their name incorrectly.
Apparently, Ninja and Yolandi Visser didn't want to let this one slide. Yolandi went on Instagram and addressed Eminem directly in a response video, saying, "Okay, so like, how would you feel if I called you Eeminem? Okay, your name's Eminem but I call you Eeminem, just because it rhymes with something you know."
Then, they roasted him with a little rhyme of their own: "Eeminem went to jail and got a bit of semen in his bum and was never seen again.
"You know, do you see how that feels?"
You can watch their response above and hear Eminem's line at the 3:00 mark below.
