Q Vocab: Big Mouth

KEy ENGLISH FLASH TUTORIAL :

"BIG MOUTH"

If you 'are a big mouth' or 'have a big mouth' it means you talk too much, especially about things which should be kept secret or avoided.

For example:

1. Fran's got such a big mouth. She's been telling everyone that I'm engaged. I wanted to tell them myself.

2. Oh no, me and my big mouth! I made Alex feel upset when I mentioned his dead cat.

3. Don't be such a big mouth. You should learn to keep other people's problems to yourself.

Don't confuse it with:

To bad-mouth. If you 'bad-mouth' someone it means you say negative things about them behind their back.

She's always bad-mouthing her friends. I really don't like it.
