With no clear single source attached to this short clip, its life online comes from its simplicity. The phrase is easy to recognise, easy to place, and works across many kinds of short videos without needing context from a film, show, or game. Creators reuse it as a quick reaction beat, especially when a visual does most of the storytelling and the audio only needs to underline scale. That flexibility is why it keeps circulating in edits, memes, and reaction compilations rather than fading after one trend.
About this sound
A short two-second voice clip saying this big, used by creators to exaggerate the size of something surprising, funny, or impressive in a video.
The clip is a brief spoken line built around the words this big, delivered as if the speaker is showing the size of something with their hands. The voice is clear and punchy, with the emphasis landing on big, so the line feels larger than its two seconds suggest. It works because it is instantly readable: listeners picture an exaggerated size before any visual payoff arrives. In a short video, it creates a quick beat of disbelief or excitement, making an ordinary object, claim, or reaction feel comically huge.
