Forbeca said:I would not, but I have heard it more than once. At the country club, at the theatre, and it's usually the men when they lose their patience with someone. I have never heard an upper class man calling someone Gallina, that's the truth. it was either Miedoso/sa, or pendeja.
I think the word "gallina" is used when it is evident that someone has the upperhand for instance, a big boy picking on the little guy is a gallina because he can't fight someone of his own size. Also, when a male fights a female he is considered a gallina.
