«يَا أَرْضْ مَا عَلِيكِي إِلَّا انَا»

The saying pictures a person addressing the whole earth and declaring that no one else stands on it except himself. This exaggeration captures extreme vanity: the speaker behaves as though every other person has vanished or simply does not count.

As a proverb, it labels someone who is deeply infatuated with himself and refuses to grant others any merit or advantage over him. It criticizes self-admiration that has grown into dismissing everyone else's worth entirely.

Apply it to someone so taken with themselves that they treat everyone else as negligible. Though worded as a first-person boast, it echoes or parodies that attitude to mock self-importance, not to praise it. It suits informal talk.
