Supercalifragilisticexpialidocious.
According to wikipedia the roots of the word have been defined as follows: super- "above", cali- "beauty", fragilistic- "delicate", expiali- "to atone", and docious- "educable", with the sum of these parts signifying roughly "Atoning for educability through delicate beauty." Started out as a joke but turned out to be a pretty good definition to describe the season.
