The Nas/Jay Z beef ended in 2001 when Jay-Z overreached and rapped about an explicit encounter with Nas’ baby’s mother. Douglas Century famously explained in the New York Times:
The usually brash and sure-footed Jay-Z seemed stunned by the fans’ rejection; in an interview on Hot 97, he apologized to the former girlfriend and to her family (though, pointedly, not to Nas). He explained that his mother had called him on his cellphone and told him he had crossed the line of good taste. ”My moms never, ever calls my cell,” Jay-Z said.
That was then. Today, 50 Cent escalated his feud with Rick Ross in the severest possible way. To say this is NSFW is to engage in understatement so strong that it borders on misrepresentation.
