Put this clip at the end of a reaction sequence, after the mistake has already been shown in full. Lead into it with a bruh soundboard button for the immediate fail, then let this line close the segment before cutting to the next scene.
About this sound
A short voice clip of a man saying in Portuguese that he does not want to live on this planet anymore, delivered in about three seconds as a flat, fed-up statement. It feels funny and resigned at the same time, the sound of someone watching something so stupid that giving up seems like the only sensible response.
