Nah, I ain't taking it back, faggot, fuck that!

from Eminem (Ft. Mr. Porter & Royce Da 5'9") – Westwood Freestyle 2010 Lyrics on Rap Genius

Meaning

Em has said outrageous shit about celebrities since his debut, what makes you think that he would stop now?

This more-so ties in with the previous line about Bubbles, MJ’s pet monkey. There was some controversy kicked up on an Eminem song, Just Lose It and MJ (and also Stevie Wonder) displayed some negativity towards how he (MJ) was portrayed in that song. Eminem is not going to apologize for anything he has ever said or done.
