Something someone (usually down or depressed) says when they don't feel like talking about it, or don't want to be in a vulnerable or in their eyes burdening situation.

if your girl says she's fine SHES NOT FINE. RUN TO HER HOUSE. DO SOMETHING

I'm fine is a lie. People may say their fine. But deep down they're not. I know this for a fact because I say I am fine all the time, when I really am not. So when someone says their fine, talk to them about it. They aren't fine in any way.

The calm before the storm.

A woman's way of letting you know she's pissed but not telling what she's pissed about. Don't ask her why she's mad, as this will trigger the dangerous "It's nothing". Just figure out what you did (even if you didn't do anything) and make it up to her soon. If you don't she'll probably complain about how you don't care about her.

You've been warned

no they are not fine

Your girlfriend isn't really fine. She wants to know if you really care. Text her. Call her. Give her attention.

If a girl texts you this, she isn’t fine.
