Place it right after the teasing line in a roast edit, then follow with the shocked sound for the reaction and the oh no no no laugh to close the bit. That order keeps the joke, the surprise and the laughter in one short sequence for friends to replay.

This short clip delivers the line your bro is fat in a teasing cartoon voice, then stretches into a long, exaggerated OHHH that lands like a crowd gasp. It feels mocking and playful, the kind of over-the-top reaction that turns a friend's size or appetite into a joke without sounding cruel. The drawn-out groan makes the insult feel like a punchline rather than a put-down.
