This song is about Courtney Love, in fact the 'In Utero' was largely written with her in mind, as 'Nevermind' was written about Tobi (can't remember second name!), his ex. The name came from a gift that courtney gave to kurt before they were together, with was a silk and laced heart shaped box with some strange things in it, and you could say that this was his gift back to her. The line 'forever in debt to your priceless advice' comes from a letter he sent to courtney. Appently, the line 'i wish I could eat your cancer when you turn black' means 'i love you' (i can't see how personally, but that's what I've read). 'Throw down your umbilical noose so I can climb right back' is a plea for the women in his life, courtney, his wife, wendy, his mum and kim, his younger sister, to support him. Though the song has many meanings, Kurt wrote some liner notes for the single, that weren't used, including thems like 'leonardo da vinci, male seahorses (who carry their young), rasism in the Old West and there are a few other I haven't listed because they're so strange I did't think people would take this seriously! These all come from the book 'heavier than heaven' an amazing biography about kurt, highly recomend it.
