Place it immediately after the pointless action appears on screen, so it answers the moment instead of introducing it. Follow it with the Oh My God Wow sound for a stronger follow-up, or lead in with No No Wait Wait when the mistake is still unfolding.

This is a short spoken Portuguese reaction clip, lasting about five seconds, in which a voice asks why someone did that, addressing them as rapaz. The delivery is exasperated and bemused, turning a pointless action into a funny call-out that feels like a friend shaking their head at you. It works as a quick, relatable response to unnecessary behaviour.
