Place it at the failure point in your edit, after a brief setup shot shows the danger coming. Follow it with the Windows XP Error Sound for a frozen beat, then close the sequence with The End Meme Sound.
About this sound
This is a seven-second Japanese voice clip of a frantic anime-style scream repeating the phrase "Yamero, shinitakunai," meaning "Stop, I don't want to die." The delivery is loud, desperate and completely overblown. It leaves listeners with a mix of shock and comic panic, turning a moment of pretend peril into exaggerated, helpless flailing rather than real fear.
