Basically this guy Brandon Carl Vedas took a massive concoction of drugs whilst chatting in an IRC channel, he broadcast it over his webcam. Onlookers were pretty much cheering him on to take more and more, even after he had allready taken a lethal amount.
I'll let you read into it more if you are interested. There are logs from the IRC channel on his dedication site. I often wonder what action i might have taken if i were an onlooker in that situation, and it saddens me to think that I probably would have been once of the people to egg him on to take more, and had a good laugh about it. Then the next day he's dead it's not so funny anymore.

Brandon Vedas died online as a crowd of virtual onlookers egged him to "eat more!" A chilling record of the Jan. 12 chat reads like an Internet version of the notorious 1964 Kew Gardens, Queens, stabbing of Kitty Genovese as her neighbors watched from their windows.
