Let's face it, not even a team of girls could write a dictionary on what girls mean, but here are some basics for you sad fellows who haven't caught on yet. Hint: We rarely mean what we say.
Good? Moving on...
We need to talk: You did something wrong and you should run for the hills.
Go ahead: I don't want you to
Are you listening to me: You're already dead. Leave and return with flowers
I don't know: I do know and I want to talk about it, but I want you to ask me to
Don't worry about it: You should definitely worry about it
I'm tired: It's cuddle time
I'm cold: It's cuddle time
Let's watch a movie: It's cuddle time
I look fat: Nothing you say will be the right answer. Leave and return with flowers
I like your shirt: Let's have sex
I'm going to assume a guy dictionary would be much simpler. Enjoy! ^.^
