It's a woman sitting on stage with a microphone, talking about female sexuality, abuse of women, lesbian seduction of minor girls, all sorts of uplifting stuff.
Here's the link to an excerpt from their website, if you'd like a sample.
Also, there's an enlightening Q&A section with such gems as these from Eve Ensler, the creator:
Women.com: What's your advice to mothers who are raising daughters?
Ensler: I would tell them to love their daughters' vaginas, and to really encourage that love. If they see their daughter masturbating, never make her feel dirty or bad. And I would encourage mothers to encourage their daughters to talk about their sexuality, to be proud of their sexuality, to draw pictures of it, paint images, write poems, erect monuments.
Women.com: Who has inspired you as performer?
Ensler: Tina Turner. I love Tina Turner. She's a woman who fully inhabits her vagina, and when I see her, I see that it's possible.
(Excerpt from here.)
I am shocked.
Man... that line would sound funny out of context. Well, ok, it sounds funny IN context, too.
