Put it right after the visual gag or failed attempt in your edit, then follow it with the cartoon slip sound for a second physical joke, or cut straight to a shocked reaction face to close the scene.
About this sound
Mi Bombo fart is a short 3.5-second fart sound effect built around a deep, drum-like boom with a silly, sputtering character. It feels cheeky, gross and deliberately over the top, turning a normal moment into a joke at someone's expense. The exaggerated low thump makes it read instantly as a prank reply rather than a realistic body sound.
