Place this clip as the reply line in an edit, right after the height insult lands on screen. Lead into it with the awkward moment sound button while everyone waits for a response, then follow it with the anime ahh sound button for the group's shocked reaction.

This 2.7-second voice clip captures Ed Elric angrily insisting that nobody calls him a pipsqueak. The delivery is indignant and over-the-top for such a small insult, which makes it feel funny and defensive at once, like a proud character refusing to let a height joke slide in front of everyone listening.
