Thread: Keeping Bobby

The context is hardly conclusive, but, apparently, Bobby is a mutual child of divorced parents. It looks like Bobby stays with father from time to time, and the person who says the bolded-out phrase warns the other one that the latter's wife will stop that practice and Bobby will no longer allowed to stay with the father.

I'm afraid this interpretation doesn't fit the overall vibe of the film. My hunch is that it might be some sort of slang or a set expression, but googling the phrase didn't help.
