Place it immediately after the mistaken claim in a short clip, then follow it with Bruh for a disbelief beat before cutting to the reaction shot. For a harsher roast, swap in Emotional Damage after the line instead, letting the second sound carry the joke while the first sets up the correction.
About this sound
A Russian voice clip lasting just under eleven seconds repeats the claim that crabs are not food in a teasing, brotherly voice. The speaker sounds confident and amused, as if correcting a friend mid-conversation with a joke only the two of them would share. It feels funny and deliberately absurd, the kind of sudden interruption that turns a missed point into a laugh.
