Place it immediately after the smelly object appears on screen, so the audience connects the reaction to the cause. Follow it with a shocked sound for the group's response, then an oh no no no laugh to turn the moment into a shared joke.
Sobre este som
This is a short Portuguese voice clip lasting just under five seconds, built around a single drawn-out exclamation about a smell. The stretched delivery makes it feel playful and exaggerated rather than genuinely disgusted, like someone hamming up a reaction for friends. It lands as light, teasing humour that invites a laugh instead of a serious complaint.
