A lot of that passive aggressive, condescending shit is done in night clubs and other social situations in which douchebaggery registers off the charts.
And yes, it can and often does quickly escalate into a full blown fight, or a stabbing or worse. At least around here.
Where I come from nightclubs can get shut down pretty quickly because of such incidents repeatedly happening to the point where the owners simply can't afford to insure the place after every subsequent incident.
Whether this stuff works depends on how low their intelligence is and how they rate on the douche-o-meter, male and female.
It does have some obvious application on the basis that the world is full of stupid, douchey people.
