Place it near the end of a short edit, just after the reveal or punchline, then follow it with Bruh or Fahhh to keep the same reaction going for the audience.
关于此声音
A short, roughly two-second vocal burst, the word 'fahh' stretched out and deepened by a heavy bass boost until it hits low and thick. It feels overblown and deliberately silly, like a tiny reaction turned into a huge thud, and it lands best as a quick, exaggerated punctuation for something absurd, impressive or suddenly dramatic.
