Why was "tantrum" trending last week?
1887, shortened form of jinrikisha, popularized by Kipling, from Japanese jin "a man" + riki "power" + sha "carriage."
(Japanese: "human-powered vehicle"), two-wheeled vehicle with a doorless, chairlike body and a collapsible hood, that holds one or two passengers and is drawn by a man between two shafts. It was used widely in the Orient but was largely superseded by the pedicab (q.v.), a ricksha driven by bicycle.
