A nymphet from a Slavic country or ethnicity.

You could use it for Eastern Europe generally if you're comfortable the Slavic suffix for non-Slavic peoples.

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.
