Okay, so you non-geology geeks may not know that creepmeters actually exist. They are used to measure horizontal movement along fault lines. Which is important information to have, especially if you live nearby.
I have co-opted the term and use it to place a numerical value on the “skin-crawlingness” of my beach finds (yes, I just made up that word). Disembodied doll heads crank my Creepmeter to 11.
