朕乃王
[zhèn năi wáng]
'朕' is an ancient word that emperors used for self-referential pronoun, meaning 'I'. '朕乃王' translates to 'I am the king', expressing authority and dominance, a way to express confidence, majesty, or grandiosity, somewhat humorously depending on the setting, as if proclaiming oneself as having kingly attributes.
