Significado: That idea, plan, or argument won't work; it's not going to succeed.

那个主意、计划或说法行不通；不会成功的。

Esa idea, plan o argumento no va a funcionar; no va a tener éxito.

そのアイデア、計画、議論はうまくいかない。成功するはずがない。

그 아이디어, 계획, 주장은 통하지 않는다. 성공할 수 없다.

A Southern way of dismissing a bad idea or argument. Like a hunting dog that refuses to follow a scent, the plan in question is useless. It's a polite but firm way to reject something — more colorful than just saying 'that won't work.'

这是南方人否定一个糟糕主意或论点的方式。就像一条猎犬拒绝追踪气味一样，所讨论的计划毫无用处。这是一种礼貌但坚定的拒绝方式——比单纯说'那行不通'更形象。

Una forma sureña de rechazar una mala idea o argumento. Como un perro de caza que se niega a seguir un rastro, el plan en cuestión no sirve de nada. Es una manera educada pero firme de rechazar algo, más pintoresca que simplemente decir 'eso no funcionará'.

ダメなアイデアや議論を退ける南部流の言い回し。獲物の匂いを追おうとしない猟犬のように、その計画は役に立たないという意味。単に「うまくいかない」と言うよりも色彩豊かで、丁寧だがきっぱりとした拒否の表現。

나쁜 아이디어나 주장을 일축하는 남부식 표현이다. 냄새를 쫓지 않는 사냥개처럼, 해당 계획은 쓸모가 없다는 뜻이다. 단순히 '그건 안 돼'라고 말하는 것보다 정중하면서도 단호한 거절 방법이다.
