Place it at the end of a reaction beat, right after the setup line lands, so the stare becomes the punchline of the scene. Follow it with Awkward Moment for the fallout, or cut to JoJo To Be Continued for a dramatic exit after the glare.
このサウンドについて
This is a very short Goku vocal reaction, lasting about two seconds, with no full line of dialogue, just a tense sound that hangs in the air. It feels irritated and confrontational, like a frozen glare that says more than words. It comes from the Dragon Ball Xenoverse stare meme, where Goku's intense expression became a shorthand for anger, disapproval and hostile reactions in short edits.
