カンカン

• Reading: かんかん
• Romaji: kan kan
• Pronunciation: /kan.kan/

Meaning

Furious, fuming mad — a level of anger much more intense than just annoyed.

カンカン describes blazing anger — someone who is absolutely livid. Unlike プンプン (cute anger), カンカンに怒る means the person is genuinely furious and possibly scary. It also describes the blazing sun (カンカン照り) or a clanging metallic sound, but the anger usage is most common in everyday speech. When someone is カンカン, you know to stay out of their way.

Examples

1. 嘘ついたのバレてお母さんがカンカンに怒ってる。 My lie got found out and now mom is absolutely furious.
2. 遅刻したら先生がカンカンだった。 I showed up late and the teacher was livid.
3. 彼女に浮気バレたらカンカンだろうな。 If she finds out about the cheating, she's gonna be fuming.

• Using as a verb directly — it's カンカンに怒る (to be furiously angry), not just カンカンする
