Bad is the lead single off of Lil West’s third studio album Vex Part 2. The song describes the relationship between West and a woman, and how they are “bad” for each other, but won’t give up and leave because no one understands them like one another do. The song is produced by Take A Daytrip & Russ Chell, as is the entire album, along with West’s previous album, Vex Part 1.
