Place it just before the embarrassing moment in your edit, then follow it with Bruh for the reaction, or Emotional Damage if the person ignores the warning and the embarrassment lands anyway.
About this sound
This 1.3-second spoken Portuguese clip says 'calma amor, não se exponha,' a light warning to someone about to embarrass themselves. It feels teasing and affectionate at once, like a friend stepping in before an awkward moment, and the humour comes from the familiar, caring way the warning is phrased.
