Today’s saying is : “Ponte las pilas” which literally means “Put your batteries in”. LOL to someone hearing this for the first time it might sound weird, but it’s a very common saying. The saying is referring to comparing yourself to being a toy or robot of sorts. This saying is used to mean: get on the ball! , straighten up and fly right! , put some effort in!
A parent might tell their child “ponte las pilas” if he or she brings home a not so great report card.
If a girl has a not so great boyfriend, her friends might say “ponte las pilas” & advise her to look for a better man.
If someone wants a promotion, but there’s a lot of competition they could be told : “ponte las pilas” and you’ll get it.
