What does it mean, when a guy says ‘be good’ but you are not in a relationship with him yet?

[Anonymous]

Because both him and you can't be bad. He has to be a bad boy and go fuck dumb sluts so to restore the balance you have to be good

[In_Trance]

It means he's a douche. Why are you talking to a douche?

[Dave31989]

Means you're wasting your time with him

and so is he

Just a saying, nothing behind it.
