Pants which are shorter than the wearer’s shirt and it appears the wearer has on no pants. The wearer is simultaneously both wearing and not wearing pants. Much like Schrödinger’s cat; which is simultaneously dead and alive in an unopened box.

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.
