Cap has been used in slang for years to mean a lie or exaggeration, with no cap meaning the opposite, total honesty. The phrase stop the cap turned that slang into a direct reaction, spreading through social media posts, gaming chats and short form video as a quick way to challenge a boast. Because the clip is only a few seconds long and instantly understood, creators reuse it across reaction edits and compilations, and it remains a standard shorthand for disbelief online.

The That's Cap sound effect is a short voice clip used in memes and reactions to call out a lie, brag or exaggeration in conversations and videos online.
This is a brief, punchy voice clip built around the slang phrase that's cap and the command stop the cap. Delivered in a firm, slightly exasperated tone, it lands like an instant fact check during a conversation. The word cap is stressed hard, giving the line a memorable snap that cuts through background noise. Listeners immediately recognise it as playful disbelief rather than a serious accusation, which is why it works so well as a reaction. It freezes an unbelievable claim for a second and lets the audience share the joke.
