What is the literal meaning of 'マスコミにバラして'?


The sentence is, 'マスコミにバラしてもいいんですよ？' What does this mean, literally?

Also, is this figure of speech frequently used? If it is, could you please
give me some instances when it is used in daily life?

Thank you.




Just to make sure you don't miss this point:

The lady is trying to blackmail the principal into firing the teacher by
threatening to spill the beans to the media, thereby damaging the reputation
of the school.

> マスコミにバラしてもいいんですよ

"I'll go to the media if I have to" or something like that. As others have
explained, the question mark doesn't really turn this into a question, it just
indicates that the speaker is looking for a response, i.e. a hidden "Does this
change your mind?" or something like that.
