本宫没空摆驾回宫
[bĕn gōng méi kōng băi jià huí gōng]
This refers to an imperial manner of speaking in ancient China where '本宫' (ben gong) means 'this palace,' indicating royalty. The phrase humorously suggests that the user has important royal matters to attend to and cannot linger, which is a playful way to leave a situation with a touch of nobility and wit.
