Place it right after the setup question in your edit, then follow it with the you what sound for a confused reaction from the other person. For a stronger turn, save it for the second answer instead of the first.
O tym dźwięku
This is a short voice clip of someone saying the two words 'maybe not' in just over a second. The delivery lands as hesitant and noncommittal, turning a simple dodge into a dry, awkward laugh. It works because the answer refuses to commit, leaving the moment hanging between yes and no for comic effect.
