Apparently this word is sweeping the nation! (I heard it started on Grey's Anatomy?)
So here's my thing with this word, and really, other pet names.
I don't have a problem with nick- or pet names for things on principle. I have nicknames for things. Even my own vagina (I go with "vaj").
Here's my thing with "vajayjay" though. Isn't it rather infantalizing?
The only reason I can see to use it, is to make the vagina seem less "scary." Like when you're a kid and these medical terms seem intimidating, or the bits and pieces you're talking about are "naughty." I've been there, I tried to find a euphemism I liked for quite a while. Until I realized the function of euphemisms. Should I, a grown woman, be intimidated by my own cunt? Do I think my vagina is naughty? Or something to be embarrassed by or ashamed of?
And so, I can't get behind these "cute" names for our vulvas/vaginas. It creates a protective barrier against knowledge, against grokking, of our parts. That's just not something I can support.
