ウザい

• 発音: /ɯ.za.i/

意味

Annoying, obnoxious, or irritating — used to express frustration with someone or something that won't leave you alone.

Shortened from うざったい (uzattai), ウザい is the standard way to call something or someone annoying in casual Japanese. It covers persistent people, nagging messages, intrusive ads, and anything that gets on your nerves. It is direct and somewhat rude, so it is typically used among friends or muttered under one's breath rather than said to someone's face.

例文

1. 毎回同じ自慢話するのウザいんだけど。
2. ウザい広告が多すぎてアプリ消した。
3. 彼氏が束縛激しくてウザいって友達が愚痴ってた。
