About this sound
A short voice clip saying "uy," used as a surprise or awkward reaction sound in memes, chat edits and quick punchline moments online.
This sound is a very short vocal reaction that comes across as a quick "uy" or "ooh" style exclamation. It has the feel of someone reacting instantly to something unexpected, embarrassing or slightly dramatic.
