Place it right after the on-screen question or accusation it is dodging, as the closing beat of the scene. Follow it with the drama button when you want the refusal to become the joke, rather than adding more dialogue afterward.
Über diesen Sound
A short three-second voice clip of someone saying 'Me reservo,' the dry no-comment line used to dodge a question without explaining. It lands as evasive and quietly funny, the audio version of stepping back, keeping your opinion to yourself and letting the awkward pause do the work instead of an answer.
