롤랑 미친새낀

The second part, michinsaekkin, is a romanised form of a Korean swear word roughly meaning crazy bastard, said here in its object form. Rolang is the name or word shouted before it, so the whole clip sounds like an angry callout aimed at someone.

The clip is just over one second long, at about 1,032 milliseconds. That makes it a single shouted burst with no build up, music or follow up line, which is why editors use it as an instant reaction button in videos, streams and soundboard chats.

This sound works best for exaggerated anger rather than real hostility, such as a bad play, a failed jump or an unlucky death in a game. Place it once at the exact moment of failure and let the sudden Korean shout carry the joke.
