Quick Definition: Conversation material for girls that stick like crack: astrology, palm reading, cosmos quizzes, celebrities, new age spirituality, any subject based on emotion and relationship dynamics.
Chick crack works because it usually reveals personality characteristics and underlying human relationships that are biologically hardwired to be interesting to women. It holds up a mirror through which women can see themselves in a way they can understand (women tend to easily understand things when referenced through emotion and imagination).
There are male versions of this too (dick crack), including conversations about sports, something visual, money, and goals. These are just conversational topics to appeal to the sexes in general.
