Idiom 38: Pull one's socks up

상황: 어떤 사람이 지금 하는 일을 충분히 잘하지 못하고 있을 때 열심히 하라는 의미에서 쓰는 말입니다. '분발하라'는 말이죠.
'기운내라'




pull one's socks up = make an effort to improve your work or behaviour because it is not good enough

My teacher told me that unless I pulled my socks up, he would have to move me down to a lowerclass.
