Nicki “The Generous Queen” Minaj more than lived up to the title when she sat down with Ellen DeGeneres for a lesson in rap beef 101. Minaj is, of course, a tenured professor of the subject, with more feuds to her name than Ryan Murphy’s dream diary. After name-dropping the talk show host on “No Frauds,” her response to rival rapper Remy Ma’s diss track “Shether,” Minaj stopped by “The Ellen DeGeneres Show” on Tuesday and basically briefed the talk show host on the ways of being a bad bitch.
