ガンガン

• Reading: ガンガン
• Romaji: gan gan
• Pronunciation: /ɡaŋ.ɡaɴ/

Meaning

A pounding headache or doing something with full force — going all out without holding back.

ガンガン has two powerful uses. For headaches, it describes an intense, hammering pain — like someone pounding your skull from inside (often from hangovers). As an adverb, it means doing something aggressively and without restraint — ガンガン行こうぜ is the classic 'let's go all out' phrase. Playing music ガンガン means blasting it at full volume. The word conveys raw, relentless intensity in both contexts.

Examples

1. 二日酔いで頭がガンガンする。 My head is pounding from the hangover.
2. エアコンガンガンにつけてるけどまだ暑い。 I've got the AC blasting but it's still hot.
3. ガンガン攻めていこう！守ってても勝てない。 Let's go on the offensive! Playing it safe won't win!
