Jensen Karp (Get Up On This) is a true multi-hyphenate. He's a writer, a gallery owner, an entrepreneur, a producer, a manager and a former rapper. And an author: the upcoming Kanye West Owes Me $300 (And Other True Stories from a White Rapper Who Almost Made it Big), due out June 7, chronicles his unlikely rise as the rapper Hot Karl. We talked about his childhood in Woodland Hills, getting bullied for loving rap and hip hop, performing at age 12, rap battles, media savvy, prognosticating trends, lapel pins, OCD, trauma, new clothes and so much more. We also took your questions over Twitter and did a round of Just Me Or Everyone.
