This is a single stretched-out 'yeah' shouted with rising excitement, lasting about a second and a half. The voice drags the word out until it turns a simple agreement into a celebration, full of energy and relief. It feels triumphant and a little over the top, like the exact noise you make when something finally goes your way and you want everyone to hear it.
