This song is about Kurt Cobain. It was first performed as "Dissed" and had different lyrics for the verse.
Courtney Love told Uncut Magazine: "I still don't understand why that one song with just three chords is such a big thing. But it's definitely got some good lyrics. That was a song about Kurt. I wrote it in Boston. So the line "dog beg," that's because there was a dog begging me for food." (Source Doll Parts Songfacts). .
