This clip is Goku Black snapping 'You scoundrel!' in a cold, superior voice, lasting just over a second. The delivery feels contemptuous and theatrical, like a villain catching someone in a shameful act and enjoying the scolding. It lands as a sharp, mocking put-down that makes the target feel small and caught out.
