   • 2010, Ono Saseo, Sutorippu shūgaku ryokō [Striptease field trip], Aozora Bunko, →OCLC:

     いやそれより驚(おどろ)いたのは、エイうるさいとついに浴衣(ゆかた)をかなぐりすてたのか、あちらこちらにシミーズ一(いち)枚(まい)

     Iya sore yori odoroita no wa, Ei urusai to tsuini yukata o kanaguri suteta no ka, achirakochira ni shimīzu ichimai

     No, more surprising than that may have been when A with persistence finally shucked her yukata, revealing a jumbled thin chemise

Possibly from 彼路(あち) (achi, “that way”) + 此路(こち) (kochi, “this way”) or 彼地(あち) (achi, “that place”) + 此地(こち) (kochi, “this place”); compare archaic あち (achi, “over there”). Alternatively, perhaps from 遠近(おちこち) (ochikochi, “far and near”). Attested from the 13th century.[1]

     When parents should call in their children, it is perverse that the children call their parents
