cellphonery
Rude and annoying usage of a cell phone in public, caused by a ridiculous novelty ring or a personal and private conversation conducted in a loud voice and obnoxious manner. Common in classrooms, elevators, and cramped bus stops.
That guys cellphonery on the elevator ruined my day.
Turn off your ringers in class, we don't need any cellphonery in here.
