What is the definition of Fabienna?

Fabienna is like a cosmic mashup of 'Fabien' (that's a French surname, remember?) and 'Fanny' (which sounds like a fun little name for a cat), but with a dash of 'nanna' thrown in for good measure, hence the nickname 'Little Nanny Fabienna'. Now, here's a sentence that's as unsettling as it is witty: "When Fabienna decided to become a professional meme maker, she accidentally started producing more existential dread than Netflix originals."
