草も生えない

• 読み: くさもはえない
• ローマ字: kusa mo haenai
• 漢字の分解: 草 (grass, internet slang for laughter from www) + も (even) + 生えない (doesn't grow, from 生える) → not even laughter grows
• 発音: /kɯ.sa.mo.ha.e.na.i/

意味

Not even funny — literally 'not even grass grows,' meaning something is so terrible or unfunny that you can't even laugh at it.

In Japanese internet culture, 草 (grass) means laughter (from the w → www → wwwww chain that looks like grass). So 草も生えない (not even grass grows) means the situation is so bad, so unfunny, or so pathetic that laughter is impossible. It's used when something goes beyond being mockable into genuinely depressing territory. The escalation ladder goes: 草 (lol) → 大草原 (huge laughs) → 草も生えない (can't even laugh, it's that bad). It represents the dead zone beyond humour.
