Rappers being generic by saying they're not going to be generic
Examples: 2 Chainz on "I'm Different," Kanye West, Jay-Z, Lil Wayne & T.I. on "Swagga Like Us"
You might be a rapper if... you say you're different than everyone else. Sure, that's just what everyone else is saying, but you're the one that's saying it this time so that's definitely different, and different is as different does, and you're just doing things differently than those other people. If you say it loud enough, it's bound to be true.
