When an anus is ripped to shreds from a man that sneaks up on him while he was sleeping, by another mans teeth and nails. Usually then he knocks the man out with a dildo and leaves.

Anatidaephobia is defined as a pervasive, irrational fear that one is being watched by a duck. The anatidaephobic individual fears that no matter where they are or what they are doing, a duck watches.

Anatidaephobia is derived from the Greek word "anatidae", meaning ducks, geese or swans and "phobos" meaning fear.
