What the hell is that kind of hack?

Wow what the pineapple. I was training at Windraider's when a sin comes back from being AFK. He accuses me of using No Delay which doesn't make much sense, but then he goes to the top of the map. The monsters start moving really fast and everything seems really laggy. Buddy chat was working just fine, I'm sure. I started getting hit randomly, the monsters randomly started dying, I and saw a windraider fly at me when I was at the BOTTOM OF THE MAP where nothing spawns. Then it killed me down there! I couldn't use any skills or change channels while it was happening. I know for a fact this wasn't lag. It had to have been a hack.
