Place this clip at the very end of a failed-warning sequence, after the mistake happens. Lead into it with the no no wait wait button as the panic builds, then let this clip close the scene with no other sound after it.
Über diesen Sound
This is a short Hungarian voice clip, about three seconds long, delivering the phrase 'Hiába mondom' — roughly 'no matter how much I say it.' It lands with a resigned, exasperated feeling, like talking to a wall after giving the same warning for the tenth time and watching it get completely ignored anyway in front of everyone.
