“Supercalifragilisticexpialidocious” is a playful, invented word that’s used to describe something extraordinarily good, wonderful, or beyond ordinary description, made famous by the 1964 Disney film Mary Poppins. It has since entered major dictionaries and everyday usage as a fun, whimsical way to say “amazing” when normal adjectives just don’t feel strong enough.
