I stumbled upon this 管を巻く, and looking up, it says that in English, it meant 'to grumble over one's wine cups.' But I still did not understand what it means. Can someone help to explain?
1 Answer
「管{くだ}を巻{ま}く」
is an idiomatic expression meaning:
"to talk incoherently (when drunk)"
"to grumble on and on (when drunk)"
I might add that repeating the same things over and over is often the characteristic of 管を巻く-ing.
