Uh, summa-lumma, dooma-lumma,
A reference to JJ Fad’s classic, “Supersonic,” but the remix. EM is right now rapping in the style of that song, and this bit of gibberish is a direct lift from the song.
In the Rap God video there is also a slight homage to the girls. The shot before Eminem begins floating shows the little dance they do before the this very line is said.
