When you have a back-and-forth email "conversation" with someone, and each of you keeps adding to the quoted thread with new information. The email go back and forth like a long-lasting volly during a volleyball game.

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.
