Why do we say “back east” and “out west” but never “back west” or “out east”?

Started watching Lost with my 15-yr-old son. I’m so excited. We will be taking a break in a few minutes to, hopefully, watch Jake Paul get the shit beat out of him

I never got in to twitter/x, but I might just start posting all the random shit I want to hear. I have no followers, so nobody will care. It’s gonna be awesome. If I remember to post.
