The "U╹ x ╹U" emote, also known as the "Asleep Bunny" emote, is a popular Japanese emoticon used to convey sleepiness or cuteness. It consists of two closed eyes represented by "U," a vertical line for the nose, and two horizontal lines for the mouth, with two small ears made from the letter "x." The emote is commonly used in online chats, social media, and messaging apps.
