• Two very famous people have the initials MJ: Michael Jackson and Michael Jordan. When asked by Pop Crush, which of these superstars the song is about B.o.B. replied: "It's not … really … about Michael Jordan. And it's not really about Michael Jackson. But it is about 'MJ.' But, it's just a reference in the song."
• So what is the song's meaning? B.o.B told Pop Crush it's him introducing his new term for ballin', "MJ-ing": "The song] is about ballin'. It's like, I feel like ballin' has grown into a universal term," he explained. "You know, anybody can say it. You know, a 5-year-old kid enlisted in minor league sports can say, 'I'm ballin'.' The CEO of a business down the street getting off of work, making choices in business left and right, getting into his car, he can say, 'I'm ballin'.' A college student could crush up the final exam, end up with a 4.0, graduate summa cum laude, they could say, 'I'm ballin'.' And that's what it's about. It's about 'MJ'-ing."
• The song features a vocal contribution from St. Louis rapper/singer Nelly.
