answer:Here is the etymology of the word coaster. 1570s, “one who sails along coasts,” from coast in verbal sense. Applied to vessels for such sailing from 1680s. Tabletop drink stand (c.1887), originally “round tray for a decanter,” so called from a resemblance to a sled, or because it “coasted” around the perimeter of the table to each guest in turn after dinner (cf. coast in verbal sense “to go around the sides or border” of something). Source Fascinating, isn’t it? I don’t know how many countries use this term for this specific use.That would be interesting to know as well.
