About this sound
A short "what's up" voice clip used as a reaction sound in memes, edits and chats when someone enters, checks in or starts a conversation.
This clip is a very short spoken "what's up" that lands like a quick greeting or a casual reaction. At just over a second long, it works best as a punchy insert between cuts rather than a full dialogue moment. The tone feels familiar, relaxed and slightly comedic, which makes it useful when a character appears on screen, when a scene suddenly shifts, or when you want to underline an awkward attempt at being cool. Because it is so brief, it adds personality without interrupting the pace of the edit.
