Lyric discussion by Boonerang 

OK so here's what I think, not that it matters, but oh well.

The song's about and independent woman's battle with PMS....yeah, I said it. Think about it, it all makes sense. The PINK (suggests feminine) robots are the PMS, and she has to defeat her own PMS by disciplining her body and taking vitamins [midol], for the narrator and everyone's sakes. Because, 'It'd be tragic if those evil robots win'. Everyone knows what women are like when those evil robots win!! Haha, but no seriously, it's not fun....

@Boonerang It sounds plausible, but when you look at the lyrics with cancer in mind, this interpretation loses strength.
