(You can pick your name, whether it be one of your personas or just a random name you think a typical rapper would have, and you can pick your opponent's name too.)

You're a famous rapper, but you were invited to rap battles to rap to roast other people, and if you had better raps and got more votes from the audience than your opponent, you'd win. Your opponent is your biggest rapping rival, who is almost as popular as you... Out of everyone else, your biggest rival!

Now you have to find good roasts in raps to really win, you'll need to win against someone who is nearly as popular as you somehow...
