A soothing mixture of cocaine and vaseline that Fred Phelps sticks up his ass before sitting on a highway cone or other large object. See Goatse.
Westboro Baptist Church pastor Fred Phelps was at a God Hates Fags rally and asked me to find him some anusthetic. Not content with a simple crucifuck or normal act of pastorbation, he had developed an urgent need to shove something very large up his poop chute.
