ok, bad teeth would be a bad thing, but there's no horsey genes amongst us!
Agree that people started making up names at some point. Ruby, Lavender, Rose, Lily, Pearl were all faddy Victorian inventions at one point and they ended up becoming standardly used names over time. And didn't Wendy actually come from Peter Pan and have no precedent?
Anyway, re: Bay, I didn't invent it!
