A person you know that only pukes in the toilet while no one is watching at a party most likely due to the extremely fast consumption of alcohol, either by means of shotgunning or bonging. Usually, a closet puker will deny that it ever happened.

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.
