Anatidaephobia

Anatidaephobia is a branch of Ornithophobia; the fear of ducks. According to Wikipedia, Anatidaephobia is the fear of somewhere, somehow, a duck is watching you. This was first a joke phobia in a comic where a man in his office sees a duck out his window all this time, but it turned into an actual phobia. There is also a lot of memes about this for some reason.
