Place this clip right after the polished Miku moment in your edit, then follow it with a shocked sound for the reaction and the oh no no no laugh as the group response before cutting back to normal footage.
Sobre este sonido
This clip is a short fart sound effect, about three seconds long, presented as a Hatsune Miku prank sound. It lands as rude, silly and deliberately awkward, turning the cute virtual singer's polished image into a quick gross-out joke. The contrast is the point, and the brief hit makes it feel surprising rather than drawn out.
