What is the definition of Unjolly01?

Unjolly01 is a delightfully absurd term that combines the whimsical 'unhappy' with a nod to the classic villainous Jolly Roger from pirate folklore. It's like calling someone a "grumpy ghost" or a "melancholy mermaid" but with a digital twist. Imagine if your best friend, who always made you laugh, suddenly turned uproarious and eerie at the same time - that's what unjolly01 would be for them.

Now, here's a chilling example sentence using this term: "Unjolly01 confronted the ghost of his childhood, demanding an explanation for why his birthday party was always postponed."
