Sorry there was so little info, I posted this in game. Basically, this guy came on and said, in nearly these exact words, "So, do you guys like it when I do this?" This was followed by the server completely locking up for a good 10-20 seconds. He laughed and continued to lag the server, saying things like, "Do you guys want me to crash it this time?" He eventually lagged himself out and we didn't see any more of him.
