嘘やん

• 読み: うそやん
• ローマ字: uso yan
• 漢字の分解: 嘘 (lie) + やん (casual copula)
• 発音: /ɯ.so.jaɴ/

意味

No way — a softer, cuter version of 嘘やろ expressing surprised disbelief at unexpected news or situations.

嘘やん combines 嘘 (lie) with やん, the softer Kansai-origin sentence-final particle that has spread nationwide through social media and TV. Where 嘘やろ sounds blunt and masculine, やん feels lighter and is used comfortably by all genders. It functions as a reflexive exclamation when something catches you off guard — a surprise celebrity sighting, an unbelievable price, or a friend's shocking confession. The tone is always genuine surprise rather than accusation.

例文

1. 推しが結婚発表した、嘘やん泣きそう。
2. このクオリティで100円？嘘やんこれ。
3. 明日テストあるの？嘘やん聞いてないんだけど。
