ヤバ

• 読み: ヤバ
• ローマ字: yaba
• 発音: /ja.ba/

意味

A clipped version of ヤバい — a quick-fire exclamation for anything shocking, amazing, or terrible, stripped down to its most instinctive form.

ヤバ takes the already versatile ヤバい and compresses it into a punchy two-mora burst. Where ヤバい can be drawn out for dramatic effect, ヤバ is an immediate gut reaction — the word that escapes before your brain finishes processing. It is even more casual than its parent form and often stands alone as a complete utterance. The truncation follows a broader trend in Japanese slang of shortening adjectives (きもい→キモ, うざい→ウザ), signalling both intimacy and urgency.

例文

1. ヤバ、財布家に忘れてきた。
2. この写真見て、ヤバ、可愛すぎるんだけど。
3. え、ヤバ、明日までのレポートまだ何も書いてない。
