After having established themselves with "grandiose" stage personas, Twiztid wanted The Green Book to be more personal in its lyrics; as Jamie Madrox explained, "We wanted people to see that inside those Shogun warriors there were people. After telling them stories about the mutants from Dimension X and all that, it was cool to try to personalize those characters more and let people into who we are as people".[1] This was particularly evident in the song "Fat Kidz", which reflected Jamie's childhood weight issues in a way that he intended to "make being fat cool. 'Be proud to be fat'. It's cool to be fat and try to empower those people who felt they were inferior".[1] It name drops numerous plus-sized public figures and fictional characters, including Biggie Smalls, Chubb Rock, Chris Farley, John Candy, Big Pun, Kevin Smith, E-40, King Kong Bundy, Fat Joe, Blaze Ya Dead Homie, Fat Albert, the Fat Boys and Grimace.[2]
AllMusic's Rob Theakston panned the album, writing that while The Green Book was an improvement over Insane Clown Posse's The Wraith: Shangri-La, "Twiztid sounds like a half-hearted attempt at a flaccid Kid Rock or Everlast recording session gone very wrong. Even appearances by the main juggalos themselves can't save this ship from sinking".[3]
On the 20th anniversary of the album, Jamie Madrox said that the album "resonated with people over a long period of time. We're proud of that".[1]
