To act without consideration for another’s feelings or interests. The term comes from the seventeenth-century practice of arming cavalry horses with horseshoes mounted with projecting nails or points. This not only gave the horses better footing on slippery terrain but also served as a weapon against fallen enemy troops. Within the next hundred years or so the term was transferred to domineering behavior, overriding others without regard or respect. An 1861 issue of the Saturday Review stated, “We have ridden roughshod over neutrals in our time.”
