Insane Clown Posse

The Good: The 6.5 million records sold by rappers Shaggy 2 Dope and Violent J are rather modest compared to most of the other bands on this list, but ICP have created something bigger -- their own society. The band's face-painted clown army known as "juggalos" conduct an annual pilgrimage to something called the Gathering of the Juggalos. It's basically the equivalent of the Muslim Hajj to Mecca, except this pilgrimage is usually to a mid-western U.S. campsite to take drugs, listen to murder-rap and watch pro wrestling.

The bad: For the average ICP fan, wondering how magnets work is a legit existential crisis.

The Disparaging Words: "I was put here to put fear/In people who spray Faygo root beer/And call themselves clowns cuz they look gay/Faggy 2 Dope and Silent Gay Claiming Detroit, when y'all live 20 miles away," rapped Eminem, homophobically, on his ICP diss-track 'Marshall Mathers.'
