Prison rapist who preys on "fish" (new prisoners) and other, weaker male inmates. The bull fruit does not regard himself as homosexual, rather, as a sort of leader figure who engages in sex with other men only because women are unavailable to him, or as a display of power. Certinly the bull fruit limits his sexual encounters to only those of his choosing, and is always the "driving force" in the sexual exchange.
