Romolo
Derived from Romulus, twin brother of Remus - the founder of the great city of Rome, thus the humble beginnings of the greatest civilization the world has ever known - The Roman Empire. Romulus slew Remus with a shovel over a dispute about which one of the two brothers had the support of the local deities to rule the new city and give it his name (Rome).
He made fun of my sister, so I was seriously thinking of pulling a "Romolo" and killing him.
