Poo poo scrapies

It's not scabies, it's not rabies, and it's kind of scrappy.
I'm thinking about how the English language lacks a word (that I know of) for the little turd marks that get left behind on the toilet bowl after the flushing of a particularly vigorous crap.  Skid marks works in a metaphorical sense, but I feel like the colloquial use of skid marks is too tied to marks left in the undergarments at present, doubling up on meanings seems short-sighted.  So I suggest "scrapies".  It's not perfect, but it's evocative of poo scraping down the side of the toilet bowl as it goes, and it has the air of residue.

Some test cases:

It's hard to look dignified when people have seen your scrapies.

or

What's less aesthetically pleasing, scrapies on a white toilet bowl or scrapies on a pastel-colored one, say pink or turquoise?

Today's second dump: very sulfur-smelling.  Not steamy at all, in my current parlance.

For I am an artist and this nice clean toilet bowl will be my canvas today.
