This is about a groupie who gets involved with one of the rappers in the song (presumably Mystikal), hence the "child support," "trying to get my papers straight," and "you better not walk in front of my tour bus" lyrics.
Comedian Chris Rock does a bit about how hard it is to defend rap music. In the old days, Rock claims, groups like Public Enemy had a lot of meaning in their songs, but there's not much you can say about this: "Well you see, the bitch is in his way, and he needs her to move."
The song features Mystikal and I-20. The latter is a member of Ludacris' rap group Disturbing The Peace.
