Once upon a time there was a girl named Allison. She fancied herself something of an actress. And she was, but not a very good one. But I digress... In 10th grade she got a (very small) part (or three) in her school's production of Macbeth. Due to the overwhelming lack of boys willing to say things like "doth" and "methinks", and the overwhelming number of girls who were willing, her character's name was Angus. There was another girl who played a character named Rosse. These two were Scottish nobleman (if memory serves correctly) and were often in scenes together. Because both Allison and this other girl had long, dark, bushy hair, it's understandable that some people might confuse them if they didn't know either of them well. A boy named Edward (but he wasn't sparkly), who either didn't mind saying "forsooth" or else had a crush on a girl in the play, took to addressing everyone involved in the play by their characters' names all the time. However, despite being friends of sorts, he couldn't keep straight which character Allison played. Was it Angus, or Rosse? More than 50% of the time he got it wrong, and he finally gave up trying and just called her Rosse and the other girl Angus. It's sort of like Rosencrantz and Guildenstern, anyway. As long as the lines got said, whether it was Angus or Rosse saying them was frankly irrelevant. Well, long story short, Allison's best friend, Pamela, who was not in the play (right? if you were, forgive me!), found this hilarious. It got shortened to Ross when written (who needs the silent "e" anyway?) and thus, a nickname was born.

Also, if anyone else has a unique nickname story, I'd love to hear it!
