I want to create a new word pertaining to poetry how could I make it official?

I want to use the word, “Potit” to describe one liner poetry.

Does one liner poetry already exist?

Here would be the definition

“Potit” is a one lined poem that describes a feeling or a place or a thing.

That’s it! It’s derivative of a “Poem” combined with “Petite”

Thoughts etc?

Here is an example of a “Potit” I made

“Fingers of patina & metal silk”
