As I said to him in chat, I always think I have a grasp on just how stupid people are, and then what the fuck do you know, someone surprises me.
The game was lagging and it was taking a long time inbetween moves. This retard was convinced that I was holding my pieces in the air and trying to drag the game out....even though I was winning. I called him every name I could fucking think of, and then I ran out. It was actually impossible to explain to him how lag works. He is honestly, the stupidest person I have ever played.
