A sanctimonious driver who leaves hundreds of feet between himself and the guy in front of him while driving in heavy highway traffic. Laggers think they are saving energy and being safe drivers but actually they induce people behind them to change lanes to get around them thereby increasing the likelihood of accidents, never mind all the stress and aggrivation they cause. They are too stupid to see that if everyone drove like them, there would be no room on the highways during rush hour.
Passenger: "Why are you driving so slow?" Driver: "Because of this fucking lagger in front of me. Just give me a second to get around him. Christ, I hate those assholes".
