This the revenge of the dicks,
Play on the well known movie “Revenge of the Nerds”
This part means that the 9 guys in OF are about to get their revenge with their 9 mills (most likely upon 2DopeBoyz). Which he references in the next part of the line. It’s a paradox because Tyler is calling OF the bully, and they’re about to do some shooting. Instead of the people who are “below” them doing the shooting like the nerds, like in the VT & Columbine shootings.
