Question: what does it mean when you add chan to someone's name?
Answer: Schwarzenegger AKA Shuwa-chan. Chan (ちゃん) is a form of san used to refer to children and female family members, close friends and lovers. The change from san to chan is a kind of "baby talk" in Japanese where "sh" sounds are turned into "ch" sounds, such as chitchai for chiisai, "small".
