Place it immediately after the failed moment peaks, then follow it with the SpongeBob Fail sound for a second reaction, or switch to the Dun Dun Dun sound when the flop turns into a serious setback.
Über diesen Sound
This is a very short AI text-to-speech voice clip, lasting just over a second, that speaks the line 'womp to the fucking womp'. The delivery is blunt and deliberately unsympathetic, which makes it funny rather than kind, turning an awkward flop into a quick punchline for anyone listening.
