A trauma contract is where one person in a relationship (romantic or friendship) makes partner(s) sign a contract saying that they will not do certain things as a result of a previous toxic relationship. This is often linked with ptsd and paranoia, as trauma from the past could make one fear similar things happening again.

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.
