Place it right after the confusing claim in your edit, as the direct response to it. Open with Ceeday Huh to set up the moment, follow with this clip as the question, then close with No No Wait Wait when the explanation starts to unravel.

This is a short 2.7-second voice clip in Javanese Indonesian slang, with a speaker asking 'maksudmu opo, cak?' — 'what do you mean, bro?' — in a blunt, questioning tone. It lands as confused disbelief, the kind of reply you give when a statement sounds absurd or needs explaining, with a dry, teasing edge that makes the challenge feel funny rather than angry.
