The act of taking a selfie while taking a shit in the upper tank of the toilet, thereby leaving for an unsuspecting friend or foe a beef stew flush on the next use.

Once the prank has been exacted on your target, posting your photo to Facebook to share with all your friends exactly who accomplished this diabolical deed.

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.
