This guy committed arceny on my neighbor.
Pronounced Ar-chen-y. Arceni is hard to describe. He is a literal demi god in looks and smarts - with the skills and abilities to overcome any and all obstacles in his path. His long hard baguette is legendary to many and beloved by more. If you ever have the fortune of meeting an Arceni then know that you are blessed.
Person A: "You know Arceni?"
