嘘やろ

Japanese Slang Japanese ★★★★★ 5/5 very-casual うそやろuso yaro
読み うそやろ
ローマ字 uso yaro
漢字の分解 嘘 (lie) + やろ (casual copula) → 'That's a lie, right?'
発音 /u.so ja.ɾo/

意味

No way / you're kidding — a shocked exclamation of disbelief, expressing that something is so surprising it must be a lie.

嘘やろ combines 嘘 (lie) with やろ, the casual form of だろう (isn't it / right?), literally asking 'that's a lie, right?' It is the go-to exclamation when something shocks you — good news, bad news, or just something absurd. The standard Tokyo equivalent is 嘘でしょ, but 嘘やろ carries a rougher, more masculine Kansai-influenced energy that has spread nationwide through internet culture and variety TV. It is everywhere: tweets, live reactions, gaming streams, and daily conversation.

例文

  1. 嘘やろ、あいつ本当に東大受かったの?
  2. 財布落としたと思ったらポケットにあった。嘘やろ自分。
  3. 推しが突然引退発表して嘘やろってなった。

正しい言い方

  • 嘘やろ、もう12月?早すぎん? (No way, it's already December? Isn't that too fast?)
  • 嘘やろ、このガチャで推し出た! (No way, I pulled my favourite from this gacha!)

避ける言い方

  • 相手の発言を本当に疑っている場面では使わない方がよい (Don't use it when you genuinely doubt someone's honesty — it sounds like a casual joke, not a serious challenge)

よくある間違い

  • Confusing 嘘やろ (disbelief exclamation) with 嘘つき (liar) — the former is a reaction, not an accusation
  • Using it in formal situations — 嘘でしょう or 信じられません would be more appropriate
