Place it immediately after the offending line in a reaction edit, then follow it with Damn for a second beat of disbelief. If the setup needs a stronger opening first, open with No No Wait Wait and let this clip close the exchange.
Over dit geluid
This is a blunt Russian-language expletive, delivered as a single sharp phrase in under a second. The clipped delivery makes it feel confrontational, exasperated and deliberately over the top, like a sudden verbal shove in the middle of a conversation. It works as a raw reaction rather than a line to quote, landing hardest when the moment already feels tense or absurd.
