jian人就是矫情c
[jian rén jiù shì jiăo qíng c]
In this name, 'jianren' could mean 'simple person' or 'slim/fit person', and 'jiaoqing' means being overly sentimental or fussy. The 'c' at the end might imply English 'cry' or just be for cool/chill. So it means a fit person who is overly sentimental, showing self-mockery humor about oneself.
