If we wanted to know how to intricately arrange cookies in a jar, we’d call Khloé Kardashian. Cat question? We’d go to Taylor Swift.

Likewise, for any and all butt-related inquiries, who better to turn to than the mastermind behind (heyo!) “Baby Got Back,” Sir Mix-a-Lot?

We met the rapper on Thursday’s Streamy Awards red carpet, where he walked PEOPLE and Entertainment Weekly Features Director Zoë Ruderman through the art of the belfie. Did you know Sir Mix-a-Lot is a professional butt photographer? Neither did we.

But it was no surprise he knew so much about butt photography once we saw the contents of his phone. Watch the video above to see both his tutorial and the text that prompted our editor to say, “I’ll get fired if I read what’s in the middle.”
