Built for BBC or Made for BBC?

We hear a lot of talk about women being "built" for a BBC or "made" for a bbc, but how does one tell the difference? If a woman is made for a bbc does that mean she was handcrafted for bbc by god? and if she is built for bbc does that mean she wasn't actually perposefully created for bbc but her body is built for taking bbc?

These are just some of the many complex questions of the universe that need answers.
