Lyric discussion by persimmon 

I've read that Lisa wrote this about an actual stalker who harassed her for years.

While I would agree with you, sin, that it's about always waiting to be attacked, I'd disagree that the narrator feels "ready" in the sense of being adequately prepared and up for the task of defending herself. To me, the song chronicles the slow but complete disempowerment and paralysis that is caused by living in constant fear.
