Put it first in an edit as the opener, then follow it with a quick reaction sound for the reply that comes next, and save a goofy sound for the punchline at the end so the sequence builds from hello to joke.
About this sound
This short clip is a loud, drawn-out greeting — 'Hey, what's up guys, yeahhhh' — delivered in a high-energy, playful voice over about four seconds. It feels upbeat, silly and instantly familiar, like the start of a joke video or a big entrance in a chat.
