Eat the cake, Anna Mae (used in Beyonce ft. Jay Z's song "Drunk In Love," is a reference to Tina Turner. Before she became uber famous, her name was Anna Mae. When she was in a diner, after she released her first single, two kids came up to her and asked for her autograph, not her husband's, Ike. Ike got jealous. He got some cake so they could celebrate, but when Anna Mae didn't want to eat it, he said, "Eat the cake, Anna Mae!" and pretty much forced it in her mouth and started attacking her. She was able to get away from her abusive partner, and start her musical career.

From Jay-Z's verse on Beyoncé's "Drunk in Love". although he got it from the movie about Tina and Ike Turner, what he is really doing is saying that Beyoncé eat his ass.
