死都不肯睡的喵星人
        
            [sĭ dōu bù kĕn shuì de miāo xīng rén]
        
        
            Translates to 'A cat person who refuses to sleep even until death'. It's used humorously by a night owl who loves cats and resists going to sleep no matter what, possibly implying staying up late browsing online.
