Question

My cousin bet someone $1000 that it is.

Answer 1

According to Mary Poppins, the word is an adjective that means great, good, excellent, and just about any possible positive adjective.

It is not a real word though.  Please see below for the etymology:

Etymology

A memorable ficticious word from the movie Mary Poppins (Walt Disney Studios, released 1964), and also the title from a song in the movie. It is not a real word, as the creator of the word simply created it for purpose of use in the movie.

Answer 2

It was coined in a song in Mary Poppins, but it doesn&#039;t mean anything.

Answer 3

It is... Even though the sound of it is really quite atrocious.

Answer 4

It certainly is a real word and is well-known, although it won&#039;t be found in a standard dictionary and it has no &#039;real&#039; meaning.
