A word for that

There's a word for that
But I don't seem to know it
Sometimes I grow a mustache
Just so I don't have to show it

The word for that
That someone somewhere chose
For that little dented skin
Between my upper lip and nose

There's a word for that
What does it start with, the word for that?
I'd sound so smart if I only knew
The word for that, perhaps you do

The word you're looking for is philtrum

There's a word for that
It may come to me soon
It dangles down in my mouth
And is often in cartoons

The word for that
It seems like such a drag
To not know what to call
That little fleshy punching bag

There's a word for that
What does it start with, the word for that?
I'd sound so smart if I only knew
The word for that, perhaps you do

Do you mean uvula?

There's a word for that
It's on the tip of my tongue
Well, actually underneath it
And has been since I was young

The word for that
Although I wouldn't quote
It likely stops my tongue
From disappearing down my throat

There's a word for that
What does it start with, the word for that?
I'd sound so smart if I only knew
The word for that, perhaps you do

What does it start with, the word for that?
I'd sound so smart if I only knew
The word for that, perhaps you do

Are you nuts, it's frenulum
