Marilyn Manson - Lunchbox Lyrics Meaning

Well, this song is about Manson's crazy childhood, specifically his years at school, where he was subject to bullies (you know him). But when picked on, he never went down without a fight. Manson, or Brain at the time, proceeded to fend off his attackers with a metal lunchbox. At some point, he said what kind of Lunchbox it was, I think it was KISS, or something like that.

And in fact, "Next motherfucker gonna get my metal" became his catchphrase through his years of lunchbox-fighting.
