超级宇宙美少女
[chāo jí yŭ zhòu mĕi shăo nǚ]
This nickname signifies someone who views themselves as an exceptionally beautiful girl with a vibrant, fantastical, and perhaps otherworldly charm. The term 'super universe' implies that this beauty or uniqueness is not just remarkable on Earth but could be unparalleled in the entire universe, expressing a very idealized and exaggerated sense of self or a persona that's full of imagination and youthfulness.
