My definition of a chick flick is usually a film that usually heavily emphasizes romance, usually when the lead of the film is female. Most 1990's Meg Ryan movies qualify as this. It's not as definitive of a chick flick when it's a romance with a male lead, as sometimes these tend to be more comedic, like There's Something About Mary.

Some films are easy to define as chick flicks, but others are a bit more ambiguous.

Haven't yet seen Memoirs of a Geisha, so I can't definitely say, but when a movie is historical in context, it's usually not a chick flick. There are some exceptions, like the Jane Austen novels that have been turned into films, like Pride & Prejudice. It does fit my definition of a romance with the lead role being female.
