look up any word, like cunt:
In reference to the televison series Hannah Montana on Disney Channel

A secret that is so substantial it could change your life immensely. Few to none know. Usually constantly contemplated as to whether or not to reveal it. Mostly in the case of putting on large guises.

(ex: Being in the closet, Witness Protection Program, Illegal Immigrant, Crime, Big High School Drama, etc.)

Refers to Miley Stewart having the secret of being Hannah Montana
I'm the only person on the planet that knows. It's like a Hannah Secret.
