Put it right after the peak of the argument or panic in your edit, then follow it with Bruh Meme once the other person answers. It works best as the turning point before a next scene, paired with a Fail Sound Meme beforehand to set up the contrast.

This three-second clip has Sylvester Stallone as Cobra speaking in Portuguese, opening with a laid-back address to a friend before telling him to stay calm and asking if he wants to talk. The low, steady delivery feels cool and reassuring rather than threatening, like a tough guy defusing a tense moment. It comes from the 1986 film Cobra, in its Portuguese dub.
