Place it at the end of a short reveal sequence, after the build-up and before a second reaction. Put Sudden Suspense Sound Effect first to set up the reveal, then let this clip deliver the verdict, and follow it with Brother Eww Reaction Sound to extend the reaction.
About this sound
Ruca delivers a Portuguese outburst aimed at a foul smell, packing a crude swear-word complaint into under three seconds. It feels shocking and funny at once, because the disgust is so direct and overblown that it works as a sudden joke built on disgust. The line comes from a clip by Kesyn & Skelter, recorded as a raw reaction rather than a scripted film or television moment.
