うるさい

• 読み: うるさい
• ローマ字: urusai
• 発音: /ɯ.ɾɯ.sa.i/

意味

Shut up, noisy, or stop nagging — used to tell someone to be quiet or to express annoyance at persistent interference.

うるさい has a range from the neutral 'noisy' to the aggressive 'shut up!' depending on tone and context. As casual slang, it is most often used as an exasperated response to someone who won't stop talking, nagging, or giving unwanted opinions. It can also describe persistent sounds, but the interpersonal usage — telling someone to back off — is the most common slang application. The blunt うるさい！ is one of the first Japanese words many learners encounter in anime.
