Dil Flakes
Created from unclean, unhygienic paractices. Found on heavily used dildos primarily under the head, under the simulated veins and other porous cracks and crevices. When left unwashed after use, the user's vaginal or anal discharge hardens and dries to a flakey consistency. It may reconstitute into liquid again upon reuse of the device. Just wash your sex toys to avoid this nastiness.
I looked in my Mom's nightstand and was totally grossed out by the Dil Flakes on her big black dildo.
