Put it at the very end of a fail clip, just after the mistake, then follow it with Emotional Damage for the reaction and Bruh if the failure was obvious. For a group fail, open with Goofy Ahh Sounds before the fall so the oof closes the sequence.

This is a short, warped take on the Roblox death sound, a single low-pitched oof lasting under two seconds. It sounds goofy and a little off, which makes a failed jump or a sudden knockout feel funnier instead of frustrating. The clip comes from Roblox, where the oof marks a character being eliminated from the game.
