Here's why it's confusing:
* Superfluity: This means an excess of something, something that is unnecessary or more than needed.
* Naughtiness: This refers to bad or mischievous behavior.
Combining these words creates an awkward and unclear phrase. It's hard to determine what the phrase might mean without more context.
If you can provide more information about where you encountered this phrase or what it was referring to, I might be able to help you understand its meaning.
