rule 404 

A pornographic, antonymous pun on "Error 404". It suggests, much unlike Error 404, that if you can think of it, that there is porn for it.

Person 1: Dude, wtf. Why would you even think of a santa-midget toe-fucking a hippo with his tounge?

Person 2: I didn't think of it... it already exists; Rule 404.
