The term used to describe a couple where both partners are cuckolds and have sex with other people while watching their partner have sex simultaneously in the same room. The cuck does not in fact make any acknowledgement to the person they are having sex with but fully concentrates on watching their partner having sex.

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.
