Place this clip right at the reaction beat after the reveal, then follow a failed version of the same moment with the bruh button for contrast. For a food gag that turns gross, swap the follow-up for fart with reverb instead and end the edit there.
关于此声音
This clip is a single drawn-out vocal hum, just the sound mmmmmmmm held for about six seconds with no words or music behind it. It feels deeply satisfied and a little smug, like a pleased reaction you stretch out on purpose to let everyone know you are enjoying the moment way too much.
