You're right - Eminem's verse on "Renegade" wasn't so much better than Jay's that the name of the song itself became slang for having a better verse than another rapper on a song.
Gotta give The Coli props in its neverending quest to try to deny all of Eminem's accomplishments. That takes heart.
Here, I'll come up with your threads for you for next week:
EMINEM DIDN'T CREATE THE TERM "STAN"
BE REAL BREHS....MMLP IS AVERAGE
EMINEM ONLY SELLS ALBUMS BECAUSE HE IS WHITE
ON 2001, HITTMAN >>>>>> EMINEM
LET'S BE REAL...EMINEM ISN'T IN THE TOP 100
Meanwhile, all rap critics, almost all rap fans, and all of Eminem's peers (literally every other rap artist) disagree with The Coli. Whenever they interview your favorite rapper, and he puts Eminem in his top 5, or he says an Eminem album is one of the best rap albums, that must really drive you crazy. It takes dedication to keep going like this. Best of luck, heroes.
