This 1932 douche ad does some Astaire-grade hoofing around the idea that "your vagina smells bad and you should be ashamed of it," dancing right up to the phrase without ever uttering it. It's a perfect satanic miracle of gendered body-shaming.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
