瞳眸赤眸
[tóng móu chì móu]
This username literally reads 'Eye Iris Red Eyes.' Red eyes can represent many different things - passionate, angry, sorrowful, crying so badly. But paired with 'Iris' in front of it, this user probably describes their own eyes which are reddish due to some intense emotions, or they simply adore such an appearance for their eyes in a fantasy or gothic way.
