He has a big mouth!

Today we will look at two similar idioms. The first is:

to have a big mouth

This has two meanings, the first is that someone can't keep a secret.

Bill: John, tell me what happened.

John: No way, you have a big mouth!

Bill: I swear, I can keep a secret.

John: No, everyone knows you love to gossip!

The second meaning is that you speak when you shouldn't, you don't know when to keep your mouth shut.

Tom: Terry has a big mouth!

Helen: Huh? What are you talking about?

Tom: I was talking to our boss about our project and she interrupted him to attack the project!

Helen: What?! Really?

Tom: Yeah, now the boss is rethinking it. That's 2 months of work down the drain...

The second idiom we will look at is:

to be a blabbermouth

This also means someone can't keep a secret. It doesn't have any other meanings.

Chris: Ted's a real blabbermouth.

Pat: Why do you say that?

Chris: Every time I tell him something private, the next day everyone in the office is talking about it!

So if you know someone that can't keep a secret you now have two ways to describe them! But remember these expressions are pretty negative so be careful.

Have a nice week,
