Put it right after the line that needs dismissing, then follow it with a Bruh sound for a second reaction before the scene moves on. For a repeat of the same joke, stack it after the Fahhh sound so the second hit tops the first.
关于此声音
This short clip is a single loud human voice stretching the word fah into a long, exaggerated yell that lasts about two seconds. The delivery is blunt and over the top, giving it a mocking, fed-up feeling that lands as a joke rather than a real shout. It works best as a quick reaction to something silly, obvious, or completely unbelievable.
