I don't speak Korean and his English isn't the best. He seemed to be yelling into the mic a lot with both languages. From what I got out of it. I think he was talking trash to the haters but can't confirm. Heard some profanity and saw some moments of him just flicking the camera off. Hung out for a few minutes but didn't see any games or replays.
I guess he's known to have celebrations and be more vocal than other players. Are his streams always like this?
