Place it at the very end of a rant or dramatic setup, after the speaker has finished, so it closes the scene. Pair it with the Bruh sound for a double dismissal, or follow an Oh My God Meme moment with it to undercut the shock before moving on.
About this sound
This is a short Russian spoken line, roughly 'Oh my God, nobody gives a damn,' delivered in an annoyed, dismissive voice. It feels cold, mocking and deliberately rude, cutting off whatever came before it with a blunt finality. Even listeners who do not speak Russian can follow the attitude in the delivery, which turns self-importance into a joke.
