While often used interchangeably by casual observers, digital linguists separate "OwO" and its sibling "UwU" into distinct emotional registers. The distinction lies in the eyes. In "UwU", the closed "U" characters signify contentment, warmth, peaceful bliss, or smug satisfaction. The face is resting, resembling a sleeping or smiling anime character.
In contrast, "OwO" denotes active visual engagement. The open eyes evoke a sudden reaction: surprise, intense focus, alarm, or feigned innocence. Over the past decade, this distinction blurred as shitposters began using OwO specifically for its off-putting, chaotic contrast when paired with grim or serious subjects.
