Place it right after the mistake is shown, so the scolding answers the action on screen. Follow it with Bruh for a reaction, or lead into Emotional Damage when the joke is about the consequences. Keep it as the single scolding beat in a short edit, with one reaction sound after it.
About this sound
This is a short Portuguese voice clip, about three seconds long, in which André Henning delivers the line about someone needing to be hit with a belt in a firm, teasing tone. It lands as a playful scolding rather than a real threat, the kind of exaggerated parental warning that makes friends laugh. Its humour comes from the blunt delivery and the familiar, over-the-top punishment it imagines.
