Place it at the moment a nickname first appears, then follow it with Bruh and finish with Oh My God Meme when the group piles on. Keep it first so the name sets up the joke, and let the later sounds carry the reaction.

Summy is a short meme clip lasting under two seconds, built around one quick burst that is easy to recognise and repeat. It feels light, silly and a little unexpected, the kind of tiny reaction that makes a chat pause for a second and smile. Its brevity is the point, giving you a fast sound for a joke that needs no setup.
