纠缠不清暧昧不明
[jiū chán bù qīng ài mèi bù míng]
This translates roughly into 'inextricable and obscure'. This sort of netname usually points to relationships filled with vague, complex emotions, perhaps entanglements between romance and friendships that cannot clearly be defined; a situation or relationship with tangled and unclear circumstances. The user probably has a history with such kind of relations, making this netname more relatable for themselves.
