Place it as the final reply after the complaint builds, then follow with the Nelson Ha Ha Sound Effect if you want the group laughing at the shutdown, or lead in with the Damn Meme Sound for a shocked setup before it lands.
About this sound
A short French voice clip, just over a second long, where a speaker delivers the vulgar phrase 'on s'en bat les couilles, Anton' in a flat, direct tone. It feels bluntly dismissive and funny, turning indifference into a personal shutdown. The wording is long-established French slang for not caring at all.
