RPH

Some measurements or tolerances are too fine to be properly measured by normal means. A useful unit of measure is an "RPH," or red pussy hair.

My first wife had red hair...and red pussy hair. And there's a lot of baggage there related to how it came to pass that I had begun to fetishize it - regardless of how well (or how poorly) she treated me. It had to do with the previous experiences in my life, relating to sex, to naked people, to pictures of naked people.

A fine thing indeed.
