There's a word for that
But I don't seem to know it
Sometimes I grow a moustache 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
horus
There's a word for that
What does it start with?
A word for that
I'd sound so smart if I only knew
The word for that
Perhaps you do?
N.C.
(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 it's often in cartoons
The word for that
It seems like such a drag
To not know what to call that little fleshy punching bag
horus
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 won't quote
It likely stops my tongue from disappearing down my throat
horus
nd on
