When you devote your life to shrek and call all of your friends DONKEH!!!.

Also when you stick a carrot up your ass and say shrek while masturbating.

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.
