The KKK stands for King Katherine's Kangaroo. It's was a highly prominent and influential institution around the bible was being written, but due to later disputes by the Australians as to the gender of Katherine, as well as the apparent Marsupianness of the Kangaroo, it later fell into disrepute.

Moses was one of the founding members of this KKK organisation, and was also the reason behind the white uniforms worn by members (for clarification, try Googling Why Moses had to grab the nearest piece of cloth he could find (a white sheet) after encountering the burning bush).
