人说短发的女孩是缺角的海
[rén shuō duăn fā de nǚ hái shì quē jiăo de hăi]
It roughly means 'People say that girls with short hair are an incomplete sea.' This net name seems romantic and slightly melancholy. Perhaps the creator of the name wishes to be different from others, implying that like the incomplete sea (a metaphor for incompleteness or a specific lack), they have their own distinctive characteristics, or possibly indicating feelings of imperfection or missing something important, especially given how the style (here, short hair) can also symbolize a unique identity.
