from The Century Dictionary.
- In an epithetic manner; by means of epithets.
Sorry, no etymologies found.
The so-called "Four Horsemen," as they were epithetically called -- Justice Sutherland, Justice Van Devanter, Justice Butler and Justice McReynolds -- were just rock-ribbed conservatives who thought that the New Deal was straight out of hell, as well as being unconstitutional, was a recipe for socialism, and they were going to stand in the way at every point along the way.
The same school probably, if a racial aspersion were epithetically cast, would have stamped it down immediately, zero tolerance.
