Place it right after the moment someone asks the question again, then follow it with Ceeday Huh before moving on. For a stronger sequence, put No No Wait Wait just before it, so the interruption builds into the question.
About this sound
This is a short spoken clip, lasting about 1.7 seconds, built around the German question 'Was habe ich gesagt' followed by the word 'Korean'. The delivery is direct and pointed, turning a simple question into a sharp call-out. It feels confrontational and funny at once, like catching someone out after they ignored what was just said.
