Arbelarosa: Picture this - it's like a cosmic concoction of the absurd, a name that sounds like it came straight from a mad scientist's lab and a Shakespearean villain's monologue. It's an exquisite blend of 'arbel' (which means 'fool' in Latin, but sounds more like a fancy word for 'crazy') and 'rosa' (which means rose, of course). So, Arbelarosa is the name of a celestial being that somehow manages to exist at the crossroads of madness and beauty.
Now, for an edgy example sentence using it: "After the Arbelarosa incident, the local bar owner decided to rename his establishment 'Arbelarosa's Foolish Fancy', a place where patrons could safely indulge in their existential crises and perhaps find solace in the company of a sentient nebula."
