What does supercalifragilisticexpialidocious mean?

Answer:
In the Song

It means great, fantastic, extremely cool. It can also be used as an exclamation, or as a way to describe something that surprises and delights you, similar to the words 'stupendous' or 'wonderful'.
It is from the song in "Mary Poppins"(1964), suggested as "something to say when you don't know what to say."
The word is a neologism, meaning it was created (for the movie), but variations existed as early as 1949.
