I recently learned the origin of the term roughshod—as in “to ride roughshod over”… Steve or the cat or my rights or even the barbecue grill.
It refers to a specific horseshoe technique. In the winter of the 17th century, a blacksmith would put the shoes on a horse with some of the nail still sticking out. The horse liked this because he could stay on his feet better on icy roads. Sort of like snow tires for the pre-industrial set.
