Most Helpful Girl
IMO, it means "I don't want you to disagree with me or tell me no."
So, I think it should mean that you don't want to be around someone who is immature, exaggerates, wants to be the center of attention, acts like their problems are so unique, so beyond belief, so much worse than anything you are experiencing.
In practice, though, I have found this gets used frequently by a person who doesn't like what you have to tell them. In fact, it's the drama queens who seem to most frequently pull this card when you are not going along with their foolishness. I guess that is because those of us who don't like drama wouldn't even waste our time telling someone they are drama, we just stop hanging out with them.
