Put it at the very end of an edit, just after the visual punchline, then follow it with Funny Ha Ha Laugh to stretch the reaction. For a drier finish, swap that second sound for Ba Dum Tss, letting the drum sting close the joke instead of adding more voices.
About this sound
Khidd is a very short Thai vocal clip, lasting about 1.6 seconds, built around a single fast, punchy spoken fragment rather than a sentence or song. It hits suddenly and feels sharp, playful and a little cheeky, giving a joke or reveal an instant local reaction. That abruptness is the point: the sound changes the mood in a beat, then disappears before it can overstay its welcome.
