Place it at the end of an exchange, after the setup has already landed, so it acts as the final word. Pair it with Awkward Moment beforehand to underline the discomfort, then follow it with Eh Eh Ehhhh when the other person keeps pushing the point.
À propos de ce son
This is a brief spoken clip built around the single word Okay, lasting about one and a half seconds. It gives a dry, resigned sense of agreement, as if the speaker is accepting something without enthusiasm or surprise. Used in that spirit, it closes a topic cleanly and signals that the point has been heard, even when the response is deliberately unexcited.
