Place it at the very start of an edit as the entrance, then cut straight to the person reacting. Follow it with the Bruh Sound Effect when the person on screen does not recognise the visitor, or the Oh My God Meme Sound when the arrival shocks everyone in the scene.

This is a very short Russian voice clip, under a second long, in which someone greets another person with a casual “Oh, hello.” The delivery feels surprised, friendly and a little awkward, like bumping into someone you were not expecting. It has spread online as a playful meme greeting, used to open a chat or react when someone suddenly appears.
