5. Spill the beans!

6. To stab somebody in the back
As Taylor Swift sings in her song Bad Blood: “(I) still got scars on my back from your knife”. Obviously, it’s a figure of speech, and it’s linked to the idiom “to stab somebody in the back”. It simply means to betray somebody.

7. To cost an arm and a leg
If you are a student and don’t earn a lot yet, you might think everything costs an arm and a leg. Fortunately, you don’t need to give those away. This idiom simply means that something is very expensive.

8. To call it a day
You might hear this idiom sometimes from your boss or your manager – but not only. If you call it a day, it simply means you are finishing for today. It can apply either for work or for studies – basically when you finish doing something which required your effort for a long time.

I can see you are tired, we’ve been working 10 hours with no breaks. Let’s just call it a day.
9. Speak(ing) of the devil
No exorcism here, don’t worry. Sometimes you talk with somebody about your friend or your colleague – and then, that person pops up or phones you. Ever been in that situation? If this happens to you, you can say out loud, “Speak of the devil!”. It means that just a moment ago you were talking about that person (in a positive or negative way, it doesn’t matter).
Speak of the devil! We were just talking about your audition, how did it go?
