dogwash
     
        /dog'wosh/ (A quip in the "urgency" field of a very optional
        software change request, ca. 1982.  It was something like
        "Urgency: Wash your dog first") A project of minimal priority,
        undertaken as an escape from more serious work.  Many games
        and much {freeware} get written this way, including {this
        dictionary}.
