Place it near the start of a hype or reaction edit, then answer it with a crowd cheer, and keep a surprised reaction ready for the reply that follows the shout.

This is a short, roughly three-and-a-half-second vocal shout in which a voice stretches out a playful request for a 'hoy yaaaa' reply. The drawn-out delivery makes it feel loud, cheeky and crowd-ready, like a call waiting for everyone to shout back. It works as a hype cue that turns a quiet moment into a shared, silly cheer.
