你再装B我报警了
        
            [nĭ zài zhuāng b wŏ bào jĭng le]
        
        
            Translating directly gives us 'if you keep showing off (being arrogant), I'm going to report you to police'. It’s colloquial Chinese slang for warning someone who is boastfully acting in a superior manner, suggesting there will be serious consequences if he continues to do so.
