You motherfuckin' chickens ain't brave enough
To say the stuff I say, so just tape it shut
“Chicken” is common slang for a coward (just ask Michael Bluth). Therefore, Eminem is criticizing everyone who picks his lyrics apart as sissies that think the same messed up thoughts as him but are to scared to speak their minds without sugarcoating anything. So instead of continuing to complain about his subject matter, Eminem suggests they either leave him alone or tape their mouths shut.
