Quite simply, someone's ass or buttocks in lieu of pain or a spanking on their rear end. Generally the party in question is too old for such treatment so it is comical and embarrassing.

The punishment is also generally done by more than one person who are in agreement of the action to follow.

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.
