Would mainly be used to call someone Stupid. But making them seem stupider than already it’s more passionate and expensive sounding.

Can also add the word head e.g Nombty Head after it to say u have a stupid brain.
( Irish slang)
You are such a nombty.
They are such nombtys.

Why are those nombty heads jumpin that fence.
