What's a Feminist Broadside anyway?

Is it a side-ways swipe across the face from a feminist? Could it be a minor swipe from a feminist against the side of your car?

Maybe a comment "at" someone from a feminist who was perceived as making a "broadside" ( in a sort of sniping manner)?

Hmmm ... I don't think so and what would these two young women have to do with a Feminist Broadside???

Have to investigate further!
