Put it near the end of a short edit, after the unbelievable claim and before the reaction shot, so it works as the witness confirmation. Follow it with the Bruh sound for disbelief, or the Oh My God meme when the story gets wilder, then close with Emotional Damage for the fallout.
Sobre este som
This is a short Portuguese voice clip centred on the phrase 'testemunha ocular', running just under ten seconds. Saying 'eyewitness' in Portuguese gives it a mock-serious, slightly dramatic charge, so it feels funny rather than formal, like someone solemnly insisting they were there when it happened.
