Über diesen Sound
A very short voice clip of a person blurting out 'OMG immigrants' in a high, startled exclamation, lasting just under two seconds. It lands as deliberately overblown and funny rather than serious, giving listeners that instant jolt of mock panic and disbelief you use when a reaction needs to be bigger than the moment deserves.
