look up any word, like cunt:
Pro-life rhetoric used to generaly refer to any form of zygote, embryo or fetus. The prefix "pre" suggests that the pregnancy will be carried to term.
Used to replace un-born which carried an idea of the possiblilty of the child never being born.
Another result of the Right Wing cognative think tanks for selective language.
Abortion kills pre-born children.
