We propose a new gender-and-organ-inclusive use of the word which means “some combination of vagina, vulva, clitoris, uterus, bladder, urethra, rectum, anus, and who knows maybe some testes.”
We're taking "pussy" back cuz we like it! The word "vagina" comes from the latin word for “sword holder.” We are not down with the idea that vaginas exist as objects of service to penises. Also, "vagina" only refers to the canal. When we refer to the canal, we still call it “vagina.” If we call the whole thing a "vagina," we ignore a bunch of other important parts, including everything you see on the outside and the clitoris which is made of the same tissues as a penis, about the same size as one, and responsible for our orgasms. (We wish we didn't have to refer back to penises to make this point about how important the clitoris is!) If we call it a "vulva" we ignore the vagina and everything else inside. So, we're using "pussy" to mean the whole thing.
