The fans of Insane Clown Posse are known as Juggalos. They mimic the ominous clown makeup of the ICP, purchase copious amounts of Faygo pop, and are under investigation by the U.S. government.
Last year, the FBI's 2011 National Gang Threat Assessment, categorized the Juggalos as a "loosely-organized hybrid gang" that are "forming more organized subsets and engaging in more gang-like criminal activity." In short, the FBI considers them a gang almost comparable to the Crips, Bloods or Latin Kings.
