Upon giving oral sex to a woman, the partner performing oral sex opens the vagina and yells "Hello, in there," or something of that sort, in hopes of hearing an echo.

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.
