이 사운드에 대해
This 11-second clip is named for the German phrase schlechte Laune, meaning bad mood, and it plays as a short reaction for someone already in that state. It gives a grumpy, fed-up feeling that lands instantly when an answer, a plan or a whole day has gone wrong, without needing a long explanation to make the point clear.
