Place it at the peak of the reveal, right after a shocked reaction, then follow it with a Fart With Reverb for a second shock and an Emotional Damage sting to close the bit.
About this sound
This clip is a short vomiting sound effect, built around loud retching and gagging noises that are easy to recognise at once. It feels gross, sudden and deliberately over the top, the kind of reaction that makes people laugh and recoil at the same time. It works best as a blunt, disgusted response to something truly awful.
