Place it as the reply beat after the repeated question, then follow it with Oh My God Wow for the stunned reaction. For a longer back-and-forth, open with No No Wait Wait before the question is asked again, so this clip becomes the payoff rather than the setup.
Über diesen Sound
This is a short Portuguese voice clip lasting about four and a half seconds, in which a speaker delivers the line 'I already told you' with a flat, fed-up tone. It feels exasperated and a little comic, the sound of patience running out after the same question has been asked once too often. The bluntness makes the rebuke land instantly without needing any extra context.
