Place this clip right after the accusation line in your edit, then follow it with the awkward crickets sound button to let the denial sit, and finish with risadinha de ladrão for a friend reacting in the background track.
About this sound
This is a short 2.3-second voice clip of Renato Amoedo Trezoitao repeating the Portuguese line asking if what he is saying is a lie. The delivery feels defensive and half-joking, like someone caught mid-argument who wants to sound innocent while also challenging the listener to prove him wrong in the moment.
