Pero esto que es has spread online as a short Spanish reaction sound rather than a clip tied to one confirmed scene. The phrase is everyday Spanish for expressing bafflement, which helped it travel beyond Spanish speaking audiences as edits, memes and chat replies. Creators reuse it when a visual needs an instant confused response without explanation, and its clear questioning tone works even when viewers only catch the emotion. It remains popular because the reaction fits many contexts, from strange objects to unexpected endings and surreal jokes.
About this sound
Pero esto que es is a Spanish voice clip of someone asking but what is this in disbelief, used for confused reactions and absurd reveals online.
The clip captures a single Spanish phrase, pero esto que es, delivered like a genuine double take. It translates to but what is this, and the tone does most of the work, rising with confusion and disbelief rather than anger. There is no music or extra dialogue to distract from the reaction, just the voice landing at the moment something strange appears. That simplicity makes it instantly readable even for viewers who do not speak Spanish, because the baffled delivery and timing signal exactly how the scene is supposed to feel.
