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.

It is another name for lube
You should always use anusthetic before anal sex.
