Place it immediately after the fail in your edit, then follow it with Bruh for a second beat and Emotional Damage to close the sequence, keeping the focus on the mistake itself.
About this sound
The clip opens with a greeting before stretching into a long, drawn-out oof that runs for about eight seconds. A voice carries the whole sound, holding the vowel out until it turns from a hello into a comic sigh of defeat. It feels playful and exaggerated, like a reaction that is too big for the mistake behind it, and it lands as a lighthearted groan rather than a serious complaint.
