Place it at the end of a setup line, just before the reveal, then follow it with a funny laugh to close the exchange, or a Yeah reaction when the speaker finally admits the truth.
O tym dźwięku
This is a sub-second vocal snippet from Hott Headzz's 'Hmmm', built around a single low, drawn-out hummed 'mmm' with no other words. It lands as a knowing, slightly suspicious hum, the kind that suggests someone is thinking something over or has just caught on. Its brevity makes the reaction feel sharp, amused and a little teasing.
