Place this clip right after the reveal shot in your edit, then follow it with Eww Brother Eww for the crowd reaction. If the moment needs a build, put Sudden Suspense first, let this line land, then close on that disgusted reply.

A short 2.5-second spoken clip of a voice calmly saying it's nothing, only the smell, as if brushing off something obvious. It feels dry, dismissive and quietly funny, because the line treats a terrible odor like a minor detail nobody should worry about, which makes it perfect for downplaying an embarrassing moment.
