Place it right after the denial in a short reaction sequence, then follow the reversal with Oh My God Wow for a bigger reaction. If the denial keeps going, add No No Wait Wait before it to build the argument, and save Damn for the final beat after the truth comes out.

This is a short Portuguese voice clip, about 1.3 seconds long, in which a speaker repeats that they are fine and then throws the claim back as a sharp question. The quick reversal makes it sound defensive, doubtful and a little exasperated, perfect for calling out a denial that nobody believes. It lands as a dry, knowing reaction rather than a loud joke.
