My favorite Half Orc was one that I named Aggro the Axe and played in a one shot game at the first NC Game Day. His quirk was that he had the same definition for "death" and "justice". This brought about such lines as:
"It smells like JUSTICE in here!"
"I'm gettin' ready to lay down some JUSTICE!"
"There will be JUSTICE before sundown!"
Also we were chasing a bard who had stolen a magica flute and set a boat on fire to cover his escape. We burst into the local constabulary, waking the deputy, whereupon I bellowed, "Wake UP man! There be flute weilding arsonists about!" Later we found a clue that told us we were on the right track: The bard's foppish hat. I gestured as though holding the hat in front of me and said, "The sort of man who would wear a hat such as this shall not be suffered to live..."
All in all, Aggro has the distinction of being one of the most fun characters that I played for such a short time.
