I think that Tori meant the song to be about how she can't get over the rape when she has sex and the guy she is with doesn't understand. So when she has sex maybe it is like she is watching the guy and someone else having sex.
To me though it is about watching a boy that you are obsessed with having sex with a different girl, and when you sleep with other guys you just keep thinking about him and seeing him in yr food. The guy that loves her is saying "you need to get over him" but she can't. The part about giving her gun a surprise is about shooting them.
