Its on K-Rino's Hitt List on the track Hitt List. He says "Eminem he gonna get fucked up cause I can't stand him......... Switch up and change my voice, Whiteboy can you do that? I'm your idol don't front you know i'm the man they'll find you slapped up and wrapped up in two stolen vans, cut up in bits and pieces............."
Funny thing is i think i read somewhere that Em listened to NIP back in the day.
