Coolio's brand new tattoo was supposed to impress his tour mates Insane Clown Posse, and their fans -- unfortunately whoever inked him up didn't use spell check.


The body art was supposed to be an homage to ICP fans -- who call themselves "juggalos." Coolio's tattoo reads "Jugalo Cool" -- ironically one 'G' shy of actually being cool.

The "Angsta's Paradise" rapper isn't losing any sleep -- telling TMZ the typo was done on purpose and he doesn't plan to fix it.
