Cover art for Lunchbox lyrics by Marilyn Manson

Here's what manson said about this song:

"The song is about being picked on and fighting back with my Kiss lunch box, which I used as a weapon on the playground. In 1979, metal lunch boxes were banned because they were considered dangerous weapons in the hands of delinquents."

About the nikki sixx thing, I guess lunchboxes were common weapons (understandably so) and it's just a coincidence.
