Place it right on the visual impact as the payoff in a fail sequence, then follow it with a Goofy Yell for the victim's reaction and a Shocked Meme Sound Effect for the onlookers. That order keeps the hit central while the reactions sell the embarrassment.
About this sound
This is a very short metallic hit, lasting well under a second, with a sharp metal ring from a frying pan striking something hard. It feels goofy and punchy, turning a plain impact into slapstick that makes listeners smile at the exaggeration. It comes from Team Fortress 2, where the pan is a melee weapon whose loud ring became a favorite for comic hits.
