Raining cats and dogs ! : Il pleut des cordes !

To be down in the mouth. : Avoir le moral à zero.

C'est un bon site web, avec les expressions anglaises. Je vais penser aux expressions que j'emploie souvent et puis je les mettrai ici. Mais pour le moment, en voici quelques dont j'ai pensé "off the top of my head":

It's a good website, with the English expressions. I'm gonna think of the expressions I use a lot and then put them here. But for the moment, here's some that I thought of off the top of my head:

"Off the top of my head" veut dire sans y penser beaucoup, par exemple:
Off the top of my head, I don't know the answer. --> Sans y penser beaucoup, je ne sais pas la réponse.

On peut dire aussi "to go bananas", qui est comme "to be nuts", par exemple:
My dog is going bananas this morning --> Mon chien est fou ce matin.

[mannimal]

To be on cloud nine : Être au septième ciel

[Thomas]

très utile: "to check out"

meaning: to look at, to learn about, to try

par exemple:
"I want to check out the new Bourne movie."

notice: "to check out" can be used, too, to imply that there is something particularly remarkable (usually a good thing) about whatever person or object you are "checking out"

par exemple:
"Hey, check out that zebra! It has yellow and red stripes!"

[mannimal]

It's the pot calling the kettle black : C'est l'hôpital qui se moque de la charité

[Thomas]

"It's Greek to me."

Litéralement, ça veut dire "C'est du grec pour moi" mais c'est employé pour indiquer que l'on ne comprend pas, par exemple:

A: "Can you help me with this math problem?"
B: "Sorry, nope. It's all Greek to me."

Alors, personne B ne peut pas aider parce qu'elle ne comprend pas les maths.

Je crois que l'on dit que c'est du chinois en français, mais je ne sais pas. Corrigez-moi, s'il vous plaît, si j'ai tort

[mannimal]

You are right. It's Greek to me : C'est du chinois pour moi.

To face the music : Affronter la situation.

[Flo]

Blind as a bat (= une chauve-souris) aveugle comme une taupe
I had a few rounds of beer with the team : J'ai pris quelques tournées de bires avec l'équipe
a hangover: la gueule de bois

[Thomas]

It's right up my alley --> C'est exactement ce que j'aime.

Another one:

"in a nutshell" --> très vite, sans trop de détails

"In a nutshell, I'm seeing lots of people this week, so I'm really busy." (mais on ne sait pas quelles personnes, ce que l'on va faire, quand, etc.)

[Thomas]

Here's another one I just thought of:

"to think twice" about something means "to hesitate"

For example, "I bought the new DVD without thinking twice because I really liked the movie."

It can also be used in the negative, for example...

"He bought a new car without thinking twice about it."

[mamour]

i've already( ) ear "on the other hand" d'un autre coté!

[Thomas]

Do you mean "I've already heard" ?
