Place it just after the bad idea appears, then follow it with the Bruh sound for the reaction, or lead into it with the Oh My God Meme sound when the danger is already obvious.
About this sound
This 16-second Portuguese voice clip delivers the line Moço, pelo amor de Deus, sai de problema in a plain, urgent spoken delivery that sounds like someone stepping in before a bad decision. It feels exasperated and protective at once, funny because the warning is so earnest, and it works best as a quick, human interruption when a friend is heading the wrong way.
