It's all over the "Kinky Kim Filthy Love Doll" -- described on the box as a "busty bubble-butt bimbo who's had more dark meat inside her than a bucket of fried chicken."

For some reason -- Kardashian believes the doll is modeled after her -- thus violating her right of publicity -- and now her lawyer, Shawn Chapman Holley, is on the attack.
