partial unbirthing

Fetish of an adult head inside a vagina. Term was created a few decades ago when the fantasy of unbirthing was broken down into total and partial types with partial unbirthing being the only remotely possible form of the unbirthing fantasy. Even then it is an extremely rare activity and the practice of partial unbirthing, as opposed to the fantasy, is not a form of Vore.

Unbirthed

When someone forcibly gets suck back into their mother's womb. It's like a black hole, but worse.

I didn't like Frank, so he forcibly unbirthed himself.

unbirthday

When you acknowledge that it is, indeed, the date of your birth, but refuse to acknowledge that you have aged.

Even though it happens to be my eighteenth birthday today, I've decided not to become an adult.
