Place it at the end of a boastful claim or an obviously fake story, just as the speaker finishes, then follow it with Oh My God Wow for the stunned reaction or Damn Meme for a flat verdict, letting it carry the punch before the next line lands.

This four-second clip is a single drawn-out sigh, the kind of slow breath someone lets out when a claim is too ridiculous to argue with. It feels weary, dismissive and quietly amused, as if the speaker has heard it all before and is not buying any of it. The sound works as a wordless verdict on obvious nonsense.
