At Bieber roast, Martha Stewart cheerfully evoked the n-word without actually saying it

You can watch the video here. Below, an excerpt:

As we all know, Kevin is one of the biggest movie stars in the business right now, and he deserves it. He struggled for years.
     When he finally got his first big paycheck, he spent $150,000 on a watch. I forget the term for that — it's not African-AMERICAN rich...
     It'll come to me...
     When I did my stretch, all the hoodrats on my cell block wanted to break off a piece of artha Stewart's ass, so I decided some bitch needed to get got.
     I walked into the chow hall, picked out the biggest bulldyke, and I stuck her.
     From then on, prison was easier than making blueberry scones.
     And Shaq, I hope your mom doesn't still hold a grudge.
