The "|/// |(ω･ )ﾉ| ///|" emote, also known as "Hiding #3," is a Japanese emoticon that depicts a person hiding or peeking out from behind a wall or object. The forward slashes represent the wall or object, while the parentheses and characters inside represent the person's face and arms. The "ω" represents a cat-like mouth or nose, and the raised arms indicate a playful or mischievous mood.
