When someone really wants to get away from a situation or relationship as fast as they can, they "run for the hills", assuming higher ground is safer. Usually it is when you are scared of something or scared of commitment.
"I told her I loved her, so she ran for the hills."
"Every time she asks me to come over, I freak out and run for the hills."
A term used to describe the stereotype of rich people (typically white folks) who run make to their safe communities after doing obligations in less desirable (black dominated, urban) communities based on the cliche of the rich people having the nice homes on the hills while all the poor people are down below.
I bet this guy cant run for the hills fast enough once this is over.
