Place it right after the confusing line in your edit, then follow it with the cat laugh meme once the joke has landed. For a longer confused exchange, start with the bruh sound and let this clip answer it, keeping the cat sounds together in one reaction sequence.

This short clip is a cat meow shaped into a questioning huh, lasting just under two seconds. The single meow carries a puzzled, almost human tone, as if the cat has just heard something it cannot quite believe. It feels funny and slightly bewildered, the kind of reaction that makes a confusing moment land without needing any words.
