Remain calm.
Comes from the Italian of “stai calmo” meaning “stay calm”
Mutated from Stai freaking calmo ( so as not to swear in public and shortened)

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.
