Minecraft wiki entry for Enderman_farming, associated text: The purpose of an enderman trap is for the easy access and killing of endermen. It is possible for the user to create such a trap that can be used by simply standing still, and looking at the endermen. This angers any you look at, luring them into the trap. Most endermen traps are best suited to the End or warped forests, as endermen spawn at a considerably higher rate there. You can still create this trap in the overworld, but endermen spawn far less often.
