Place it immediately after the on-screen name question, then follow with Awkward Crickets before anyone answers. For a lighter cut, put Chipmunk Laugh after it instead, letting the laugh close the exchange.
About this sound
A 0.6-second voice clip processed with a voice-changing effect, built around a short request to say a name. Its clipped, altered delivery feels playful and awkward, like a half-finished reply sent before thinking. It works as a shrug in audio form, quick to recognise and easy to drop into a joke.
