Hellavator was created from a K-pop band called Stray Kids. Now, this isn't a real word but the word is used as a term in their song. So supposedly, Hellavator is a elevator that takes you to hell.

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.
