It’s going to be a busy day on the National Mall tomorrow. There’s the pro-Trump Mother of All Rallies, the anti-Trump March to Protect American Democracy, several weddings and, most notably, there’s the Juggalo March.

If you’re not familiar, the Juggalo March is a rally organized by longtime extreme hip-hop group Insane Clown Posse in response to the FBI’s designation of its fanbase—proudly known as “Juggalos”—as a gang. ICP and its fanbase are none too happy with the classification and, as such, have organized tomorrow’s rally on the mall to protest. Not only is it expected to be one of the largest Juggalo gatherings in the group’s nearly three-decade history, but it’s also the first time ICP will perform in D.C., which, according to the group, was no easy feat.

Everything you need to know about Insane Clown Posse, Juggalos, and the story behind tomorrow’s march is outlined—quite poetically—by the group itself, Violent J and Shaggy 2 Dope, in the video below. See you on the Mall tomorrow, Ninjas.
