Place this clip right at the physical action in your edit, then follow it immediately with a shocked sound for the reaction shot, and finish with the oh no no no laugh as the scene cuts away to the group response.
Über diesen Sound
This clip is a short 1.3-second fart sound effect, a single blunt burst with no voice or music behind it. It lands as rude, silly and instantly awkward, the kind of noise that breaks a serious moment and makes everyone nearby pretend they did not hear it while trying not to laugh.
