Place it just after the surprising line in a reaction edit, so it becomes the answer rather than background noise. Follow it with Oh My God Wow for a bigger reaction, or use Eww Brother Eww next for a second reaction in the same edit.

This two-second clip is a woman's voice saying 'uuh, girl' in a slow, knowing drawl that stretches the first sound. It lands as amused disbelief, the kind of reaction that says something surprising has just happened without spelling it out. It feels playful and a little cheeky, with a teasing edge that makes the listener smile.
