What’s the meaning of “she has some mouth on her”? enter image description here

The idiom comes from an episode (S03E03) of Seinfeld:

-He loves that pen.
-Come on.
He talks about it all the time.
He goes on and on about how it writes upside down, how astronauts use it.
He never should have offered it.
-He didn't think you'd accept.
-Well, he was wrong.
I know his wife.
She has some mouth on her. She'll tell everyone in the condo now that you made him give you the pen. They're talking about it right now.

    I can't find a definition, although there are quite a few examples on the Internet. In general it means that the person of whom this is said uses language appropriate to a men's locker room or Army basic training. If @cobaltduck thinks there's another interpretation, it would be interesting to hear it. This particular quotation seems to be from an episode of Seinfeld, and I doubt a full text would provide defining context.

    @Xanne--You were right the first time; don't second guess yourself. When you say someone "has some mouth on her," you mean she uses coarse language and swears a lot. She speaks inappropriately. And you pronounce it with primary stress on both "some" and "mouth." Oct 27, 2017 at 20:46

    The original term was 'mouthy' meaning prone to talk back. That became 'some mouth' later, I believe.

    It's important to note that the phrase some mouth on her has to have the some stressed. That means her mouth is notable, and in this context mouth means the way she talks, which is judged as being outside some social convention by the speaker (who was probably a man). Oct 27, 2017 at 22:28

    @StevenLittman I think in this context it means that she talks a lot, which is still judged inappropriately, but it's more about being a gossip than about swearing. Mar 15, 2018 at 18:34
