ヤバい

• Reading: ヤバい
• Romaji: yabai
• Pronunciation: /ja.ba.i/

Meaning

Dangerous, risky, or sketchy — the original meaning of やばい before it also became a positive exclamation.

Before やばい became a catch-all word for 'amazing,' its original and still-active meaning is 'dangerous' or 'sketchy.' Older speakers primarily use it this way, and even younger speakers reach for it when something feels genuinely risky, unsafe, or suspicious. Recognising which meaning is intended — the classic negative or the modern positive — depends entirely on context and tone.

Examples

1. あの路地裏はヤバいから夜は絶対通らないほうがいい。 That back alley is sketchy, so you definitely shouldn't walk through it at night.
2. その話ヤバくない？警察に相談したほうがいいよ。 Doesn't that sound sketchy? You should talk to the police about it.
3. あのサイト、個人情報抜かれるらしいからヤバいって。 That website apparently steals your personal info, so it's seriously sketchy.
