He ain't mocking though like a hipster he's playing it up there's a difference. He loves hip hop it's all he does while a hipster uses hip hop to say he's better than that. Riff Raff not only says he isn't better, he'll get BET and WSHH tats as a fukk you to people thinking he thinks he's better. It's also a fukk you to "hip hop guardians" who think they control music and culture when they own jack shyt.
He's mocking elitists by fully embracing the retarded parts of hip hop. "Im gonna be so fukking retarded talkin about versace beans and shyt and your hate can't hurt me that you got nothing" while working on his skills and hustle cause he loves the culture so much. You see the snoop vid and how he was acting like a stan? that's real.
He's becoming a real talented musician too as his progression from G's to Gents/Kokayne Dawkins to Versace Python/Lil Mama/Bird on a Wire shows
this guy sorta gets it:
