A word that you can say when you have no words to say something. The word is quite vague and can mean a variety of things. It can be a compliment, or just something to say for fun. This word is the longest word in the English language, however it originated from the movie Mary Poppins, so it is usually not considered a real word.
You’re supercalifragilisticexpialidocious!

This word is very long and it shows that something is great or extraordinary. In the song meant for this word, Mary Poppins says it's used as "something to say when you have nothing to say."
