Place it right after the surprising moment in your edit, then follow it with a scream meme for a bigger reaction or an oh my god meme when the twist needs a spoken reaction, keeping the sequence short so the joke stays focused on one twist.

This clip is a single drawn-out vocal cry, spelling out a long aiii followed by a shorter aiii, lasting just under four seconds. The stretched first note makes it sound startled and over the top, while the quick second note lands like a relieved laugh after the shock. It works as a comic reaction to a surprise, a fail, or a moment that leaves someone lost for words.
