BWFW

By Women For Women.
This term can be applied to a work, a genre, a business, etc. It means that it's produced by females and targeted at a female audience.

1. Yaoi is overwhelmingly created and consumed by females; gay/bi males are a relatively small group.
2. Some insurance companies specifically target women, but this would only be a true example of BWFW if the company's employees (and management in particular) were themselves mostly women.
