to be in a state of peace, or in a good situation
to take something too far, to ask too much, or to ask for too much
I haven't heard talk greasy. But if I were to guess, I would say either a smooth talker or a sweet talker - someone who can get you to do something just by the things they say. Or it could be a guy who thinks he can get his way or get you to do something but isn't good at it. (one who uses cheesy pick up lines).
