你特么没种滚远点毛线
[nĭ tè me méi zhŏng gŭn yuăn diăn máo xiàn]
This is a rather rude username translated as 'Fuck off if you don't have balls - what bullshit!'. The tone is aggressive and confrontational expressing intense anger or contempt towards somebody else or situations they disagree with, though not suitable in polite conversation it shows the person doesn’t tolerate hypocrisy, cowardice or injustice.
