If you’re unfamiliar with Lil Mabu, here’s a primer: He’s an 18-year-old drill rapper from New York City whose rap style is reminiscent of Kay Flock or maybe even 6ix9ine. Unlike the majority of his New York drill counterparts, Mabu doesn’t hail from Brooklyn or the Bronx. Instead, Lil Mabu is from the Upper East Side, grew up in a wealthy family, and attended an elite private school.
