Pronounced sān hā nǚ, this refers to girls or ladies who are fervent advocates of Haagen-Dazs, Jurgen Habermas and Harry Potter. In other words, sān hā nǚ is a respectful title for intellectual women who also prefer the "finer things" in life.
Let's put it into context:
Phil: Hey Allen, have you seen Rebecca lately? She's looking for someone to watch the latest Harry Potter movie with. I thought you might like to go.
Allen: Cool! I've been looking forward to it. It's the final adventure in the Harry Potter film series. I never knew that Rebecca liked such things, as she is always eating Haagen-Dazs ice cream on campus.
Phil: Don't you know that she is a sān hā nǚ? She is also fond of Jurgen Habermas.
Allen: Well, I think I need to get reacquainted with her then.
