The quote means nothing because it hinges on a word that's used meaninglessly. Like so many words and expressions that are coined and quickly forgotten, it exists to signal being part of some group rather than to communicate. Based, or something.

If it were an existential concept aimed at describing some kind of Sartrean fulfillment, it wouldn't be communicated using that word.

It vaguely suggests retaining elements of black ghetto culture when you become wealthy through rap music. Real talk, keep it real, fr fr. - it's all nonsense.
