The clip circulates online under its Japanese title Potsusan 2 Echo, with the echo marking it as a processed variant of an earlier short callout. Its exact original recording source is not widely documented, so its spread has happened mainly through soundboards and short video edits where a brief echoed name works as an instant reaction. Users keep reposting it because the effect is recognisable in under two seconds and needs no context to understand, making it easy to drop into streams, gaming highlights and meme compilations without explanation or setup from the creator.

Potsusan 2 Echo is a short Japanese voice clip with a strong trailing effect, used as a meme reaction sound for funny callouts, streams and video edits.
This is a very short Japanese voice clip that says the name Potsusan with a strong echo layered over the second version. The voice is clear and close at first, then the echo makes it trail off and feel larger than the recording itself, like a call shouted in an empty hall. Because the clip is only a couple of seconds long it lands instantly as a punchline, turning a simple name call into something dramatic and slightly absurd. Viewers hear it as a playful announcement rather than a serious shout, which is why it works for comedy edits.
