When you date a guy who's very athletic and used to hard workouts, and he brings the serious dick (D) to the point of exhausting you. The dick was so serious you might have to take an advil afterwards to recover.

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.
