ずるい

• Reading: ずるい
• Romaji: zurui
• Pronunciation: /dzɯ.ɾɯ.i/

Meaning

That's unfair! So lucky! — used to express playful jealousy or protest when someone has an unfair advantage.

ずるい traditionally means 'cunning' or 'unfair,' but in modern slang it has evolved to express playful jealousy and envious admiration. When a friend gets free concert tickets, eats amazing food, or has a naturally beautiful face, the response is often 'ずるい！' It is less about genuine unfairness and more about lighthearted protest that someone is getting something you want. The tone is always playful, never truly angry.

Examples

1. えー有給取って旅行？ずるい！私も行きたい！ Wait, you took paid leave to go on a trip? No fair! I want to go too!
2. そんな可愛い顔に生まれてずるくない？ Being born with such a cute face is unfair, don't you think?
3. 彼氏にサプライズされたの？ずるい、羨ましすぎる。 Your boyfriend surprised you? So unfair — I'm so jealous.
