The exact origin of this clip is not tied to a widely documented film, show or viral creator, and it circulates online mainly as a short, reusable reaction sound rather than as a quote from a famous scene. Its appeal comes from how universally the phrase works: almost anyone can picture a moment when they heard something they were not ready to accept. That flexibility has kept it in rotation for meme edits, reaction videos and short-form clips, where a brief voice line can carry the whole joke without needing context from its source.
Sobre este som
A short voice clip of someone saying they do not know about that, used as a doubtful reaction in memes when a claim seems questionable or hard to believe.
This is a very short spoken reaction clip, lasting under two seconds, in which a voice delivers the line I don't know about that with a flat, uncertain tone that lands somewhere between scepticism and polite refusal to agree. There is no music or background noise to distract from the words, so the hesitation itself becomes the joke, making the listener pause and reconsider whatever was just said. It works best as a quick cutaway after a bold claim, an unlikely excuse or a plan that sounds too good to be true, because the deadpan delivery undercuts the moment without shouting or overexplaining it.
