“Anatidaephobia: the fear that somewhere in the world, a duck or a goose is watching you. Not attacking or touching, just watching you …”
The word first appeared in a Far Side comic by Gary Larson. Since then however, “the concept of anatidaephobia has worked its way into popular consciousness and is now often presented as a real type of phobia.”
The fear of ducks phobia can be a debilitating anxiety condition, wherein, no matter what one is doing or where s/he is in the world, they feel the constant presence of a duck or goose.
