I'm currently trying to read a japanese novel and I found this expression :
It was meant to qualify a character, but I just don't get it. At first I thought it could mean "tell one and give back ten", so I thought it meant this character tends to do more than he was actually asked or intended to do...? However, I tried searching on japanese sites and it seems it's a saying to qualify a very proud person...? Still I would like to have a more precise idea of what it could really mean and where it does come from, because I'm very interested by japanese idioms. Does anyone have a more precise idea ? Thank you very much.
