The "w( °ｏ°)w" or "Woah #2" emote is typically used to express surprise, amazement, or admiration. The two "o's" in the middle of the face represent wide-open eyes, while the curved lines above and below them represent raised eyebrows and an open mouth, respectively. It can be used in a variety of contexts, such as reacting to something impressive or unexpected, expressing disbelief or shock, or simply showing excitement.
