Is the phrase, “treat 'em mean, keep'em keen,” actually grounded in truth?

From personal experience when I have been the “mean” girl in the past, men have always been SO much more eager to please me or to try and make me happy whereas when I’ve been all happy and loved up to the point where I would do anything for them, they have seemed to take me for granted.

I’m not an advocate of being a bitch or messing with a guy’s head but I’m so much more careful now when I’m a relationship with how much I give to the other person.

Guys, do you prefer a girl who doesn’t make her feelings entirely clear and treats you “mean”?
