What does it mean exactly?


The literal meaning is:

  • C’est → It’s
  • Un truc → A thing
  • De → Of
  • Malade → Sick (people)

It means “It’s amazing/crazy” and aims to describe an incredible experience, story, place, person… or anything exceptional. It’s generally used positively, even though not always, just like in English “It’s sick/crazy” can be negative.

This expression was at first very “slangish” and familiar, reserved to very young people. But with time it became so popular that a lot of people from different generations are using it right now! (It’s still familiar though.)

You probably won’t see it in French classes because the “academic” way to say it would be “C’est fou“.

How to use

You are visiting Paris and someone asks you what you think of the city, you can say: “C’est un truc de malade  !” (That’s sick!)

You can also use it in a sentence, for example: “J’ai découvert qu’on va bientôt conquérir la planète Mars. C’est un truc de malade !” (I discovered that we will soon conquer planet Mars. That’s really crazy!)

If what you are talking about happened in the past, use instead “C’était un truc de malade !” (It was sick/really crazy!)

And if it will happen in the future, you can say: “Ça va être un truc de malade !” (It will be sick/really crazy!)
