Candaulism is a sexual practice or fantasy in which a man exposes his female partner, or images of her, to other people for their voyeuristic pleasure.

The term may also be applied to the practice of undressing or otherwise exposing a female partner to others, or urging or forcing her to engage in sexual relations with a third person, such as during a swinging activity. Similarly, the term may also be applied to the posting of personal images of a female partner on the internet or urging or forcing her to wear clothing which reveals her physical attractiveness to others, such as by wearing very brief clothing, such as a microskirt, tight-fitting or see-through clothing or a low-cut top.

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.
