The clip comes from a green-screen template featuring comedian Tim Robinson delivering the line, which creators have reused as a ready-made reaction shot. Shared widely in short-form edits and meme videos, it became a shorthand way to pause a boast and invite doubt without adding narration. Its staying power comes from its flexibility: the same few seconds work for sports takes, gaming fails, cooking experiments and everyday overconfidence, and it pairs naturally with other questioning reactions like You What? for a quick back-and-forth exchange.

Tim Robinson skeptically asks 'You sure about that?' in this short reaction sound, used in memes and edits to question a bold claim or dubious choice.
This is a short spoken reaction clip of Tim Robinson asking, 'You sure about that?' in a dry, doubtful tone that lands somewhere between genuine curiosity and open disbelief. His delivery is quick and pointed, with a slight rise at the end that makes the question feel like a challenge rather than a simple check. Played over a confident statement, a risky plan, or an obviously questionable choice, it instantly undercuts the moment and invites the audience to laugh at the gap between what was said and what is clearly true. It works because the doubt sounds casual, almost polite, while still saying the quiet part out loud.
