四方的女流氓
[sì fāng de nǚ liú máng]
This literally means 'Female Punk/Vandal/Hooligan of Four Directions.' This kind of username could imply rebelliousness or non-conformity. 'Four directions' represents all around; 'female hooligan' might mean someone doesn't want to stick to traditional stereotypes of girls being gentle but would be free and perhaps bold, rough, unconventional and maybe even mischievous.
