アツい

• 読み: あつい
• ローマ字: atsui
• 発音: /a.tsɯ.i/

意味

Fired up, passionate, or intense — not about temperature, but about someone's burning enthusiasm.

When written in katakana as アツい, this word shifts from its literal meaning of 'hot' (暑い/熱い) to describe someone who is passionately fired up about something. An アツい person gives 110%, delivers impassioned speeches, or throws themselves into a cause with visible intensity. It can be admiring (wow, they really care) or slightly teasing (they're being a bit much). Common in sports, anime fandom, and workplace contexts where someone is noticeably more enthusiastic than the norm.

例文

1. あの監督のスピーチがアツすぎて全員泣いた。
2. アツい男だよね、何でも全力でやるから。
3. アツい展開が好きだからスポーツ漫画ばっかり読んでる。
