A struggle broke out on bus line 62 between two passengers over an open window on an air-conditioned bus.
Tempers flared when a woman toting a suitcase opened the window and sat next to it. This act seemed to upset a man, at which point another passenger started to film the scene. Other passengers looked on, occasionally acting as the jury and shouting out judgments.
The argument between the pair goes on for several minutes, during which the woman gives the man what Shanghaiist hilariously terms an "angry lapdance." In phase 2, the conflict escalates to pushing, shoving, smacking and, finally, irritatingly dramatic wailing.
For reasons not entirely clear, the video, which was posted on Monday, has become a hot video on Chinese video-sharing sites. Judging by the video comments, the video's popularity seemingly has to do with the woman sitting on the man's lap, so if you're viewing this in hopes of catching a whiff of sexiness, here's a tip: Turn the sound off.
