你的她没我二分之一的好
[nĭ de tā méi wŏ èr fēn zhī yī de hăo]
The username claims that the girl referred to as 'your she' ('your girlfriend' or 'the girl you have') is only half as good as the user speaking. There is a self-appreciation component combined with comparing themselves more favorably to another significant figure in someone's life.
