0u0

0u0 is a text-based emoticon used in online communication to convey a surprised, cute, or curious expression. It is formed from three characters: two zeros as eyes and a lowercase u as a rounded mouth, creating a symmetric face: 0u0. As a simple ASCII facial representation, it is easy to type in plain text without special formatting.

In practice, 0u0 appears in chat messages, forum posts, comment sections, and streaming chats. It signals affect without words, often indicating affection, wonder, or innocent astonishment. It is part of a broader family of emoticons and meme-driven expressions such as owo and uwu, which share a playful or endearing tone and are popular in internet culture.

Origins of 0u0 are informal and not well documented, as is common with many ASCII emoticons. It likely emerged within early online communities and has persisted across various platforms into the present, supported by ongoing memes and kawaii aesthetics. Its usage tends to be lightweight and non-serious, suitable for reacting to cute or surprising content.

Variations of the form exist in some communities, including capitalization or slight alterations, though the base 0u0 remains the most widely recognized. See also: other emoticons used to express similar emotions, such as uwu and owo.
