Lord Jamar has a long history of dissing Eminem, often on Vlad TV.

Shady addressed the Brand Nubian rapper-turned-media personality's constant barbs -- which tend to be different variations of "the hood doesn't listen to Eminem" and "Eminem is a culture vulture"  -- in the Kamikaze track "The Fall."

And far as Lord Jamar, you better leave me the hell alone
Or I'll show you an Elvis clone
Walk up in this house you own, thrust my pelvic bone
Use your telephone and go fetch me the remote
Put my feet up and just make myself at home
I belong here, clown, don't tell me 'bout the culture 

That didn't get Jamar out of Shady's system, because he had some more harsh words for him during a concert in  Abu Dhabi that also featured his D12 bro Mr. Porter.

"Mr. Porter, I had a dream I was a fuckin' nobody and sucked at rap," he said on stage. "And then I wake up, you know who I was Mr. Porter? ... Lord Jamar."

Should Eminem keep mentioning a "nobody" like Jamar's name, or is it time he leaves it alone?
