Birthing Hips 

When a person has a pelvic area that looks suitable for birthing.

One friend to another:
Boy those sure are some birthing hips you got their.

Your aunt who lives in the old country:
Girl you should find a nice boy and have a nice bunch of babies with him having those birthing hips and all.
