When a person adds someone on Facebook solely because he/she finds them attractive. Even though they do not live in the same city, have friends in common, or have ever seen this person in real life.

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.
