This is a song about skulls and stuff. It's sort of a song about how everyone has a skull and every person you bring into your like has a skull. The more people you have in your life, the more skulls you have in your life. It's also a song about how we're all gonna die.
Oh yeah, I marked it "explicit," not cuz it has any curse words in it, but there's a mention of smoking pot. I'm still not certain whether that merits an "explicit" tag or not.
