Super... calif... ragil... istic... expialid... ocious!

That's not a word.

Of course it's a word. And unless I'm very much mistaken, I think it's going to prove a rather useful one.
When trying to express oneself it's frankly quite absurd
To leap through lengthy lexicons to find the perfect word
A little spontaneity keeps conversation keen
You need to find a way to say precisely what you mean

Supercalifragilisticexpialidocious
Even though the sound of it is something quite atrocious
If you say it loud enough you'll always sound precocious
Supercalifragilisticexpialidocious

Um-diddle-diddle-diddle-um-diddle-ay
Um-diddle-diddle-diddle-um-diddle-ay

But it doesn't mean anything!

Um-diddle-diddle-diddle-um-diddle-ay
Um-diddle-diddle-diddle-um-diddle-ay

It can mean exactly what you want it to.
When stone age men were chatting simply grunting would suffice

Though if they'd heard this word they might 'ave used it once or twice

That's right.

I'm sure Egyptian pharoahs would have grasped it in a jiff
Then every single pyramid would bear this heiroglyph
Oh supercalifragilisticexpialidocious
Say it and wild animals would not seem so ferocious

Add some further flourishes it's so rococcococious

Ah

Ah

Ah ah ah ah

Supercalifragilisticexpialidocious
Um-diddle-diddle-diddle-um-diddle-ay
Um-diddle-diddle-diddle-um-diddle-ay
Um-diddle-diddle-diddle-um-diddle-ay
Um-diddle-diddle-diddle-um-diddle-ay

The druids could have carved it on their mighty monoliths

Oh, yes.

The Ancient Greeks I'm certain would have used it in their myths

I'm sure the Roman Empire only entered the abyss
Because those Latin scholars never had a word like this

Supercalifragilisticexpialidocious

If you say it softly the effect can be hypnotious

Check your breath before you speak in case it's halitotious

Oh, Bert!

Supercalifragilisticexpialidocious
Um-diddle-diddle-diddle-um-diddle-ay
Um-diddle-diddle-diddle-um-diddle-ay
Um-diddle-diddle-diddle-um-diddle-ay
Um-diddle-diddle-diddle-um-diddle-ay

Of course, you can say it backwards, which is suoicodilaipxecitsiligarfilacrepus.

She may be tricky, but she's bloody good.

So when the cat has got your tongue there's no need for dismay
Just summon up this word and then you've got a lot to say

Just pick out those eighteen consonants and sixteen vowels as well
And put them in an order which is very 'ard to spell
