Uh...no, it means that the girl does not want to put up with the mind games chicks play with each other. The acting all nicey-nicey to your face only to find out that the chick is jealous of your looks, your friendship, whatever. Or that you said something and your chick friend is reading all kinds of meanings into what you said and you didn't even mean anything by it in the first place. Oh and let's not forget PMS. Jesus-the-fuck-Christ, I already have to deal with my own hormones, I don't want to deal with her bitchy ass too.
Most guys don't sweat the small stuff and if something bothers them they will say something, you may argue, but it will end. Women will hold on to it for years.
There are exceptions, always, but in general this is what I have found.
