Place this clip at the end of a confusing speech segment in your edit, right after the original line finishes. Pair it with a huh sound just before it to build the reaction, then follow it with a damn reaction once the confusion settles.

This is a short Indonesian voice clip, about five seconds long, of someone asking 'ngomong apa dia' — what is he saying. It sounds confused and a little exasperated, like the listener has completely lost the thread. That bewildered, amused disbelief is what makes it land as a reaction to rambling, unclear, or nonsense speech.
