We need a term for those menaces to themselves and society who walk halls, malls, sidewalks and, especially, across streets engrossed in cell phones -- talking, or, heads down, texting, playing games, checking the market, surfing for porn, completely oblivious to people and traffic. Target Practice, Future Hood Ornament, Dead Ringer and Road Kill seem too violent. How 'bout Cell-o-pain? Textdestrians? The Walking Droid?
