The clip is credited to TreyNotFunny through its Sound Effect Pack #1 listing, where it appears as a short, standalone reaction sound rather than a line lifted from a film or television show. On meme soundboards it has circulated as a quick way to flag surprise, admiration or disbelief, in the same family as a bruh reaction. Its brevity is part of the appeal: creators can drop it into edits, streams and reaction videos without interrupting the main audio, keeping the joke fast and instantly recognisable.
このサウンドについて
A drawn-out dayummm reaction from TreyNotFunny, used when something surprising, impressive or funny appears on screen in short videos and memes.
This short clip captures a single, stretched-out dayummm delivered in a playful, exaggerated tone, rising in pitch before trailing off as if the speaker cannot quite believe what they just saw. Lasting just over two seconds, it lands instantly and needs no setup, making it perfect for a quick reaction beat in a video. The delivery feels half impressed and half amused, so it works just as well for an unexpected reveal as for a deliberately over-the-top compliment. Listeners hear the surprise first, then the humour, which is why the sound turns an ordinary moment into a punchline without any extra explanation.
