Place it at the start of a reaction edit as your entire greeting, then cut straight to the other person leaving. For a two-beat refusal, follow it with the Nope Meme Sound Button so the shutdown lands twice without you adding any dialogue.
About this sound
This is a just over three-second Russian voice clip of someone saying 'Privet, nadoel,' a curt hello that means the speaker is already fed up with you. It lands as exasperated and dismissive, the kind of greeting that shuts a conversation down instead of starting one, with annoyance packed into two short words.
