Leave it to Amanda Palmer to add another euphemism for vagina to our language. I've never heard Map of Tasmania used before, but I kind of like it. Gives it a global, world traveler feel. I got to hand it to Palmer, she is a gutsy chic that puts it all out there (literally) and has absolutely no fear. Plus, she's recently married to Neil Gaiman, which gives her additional awesome points in my book.

If you don't know Amanda Palmer, get to with a quickness. She is the patron saint of all things wackado and a total badass, and therefore an honorary member of the Geek Girl Nation!
