Okay, so to start off this song is a hidden track on Dookie. It was written and composed by Trè himself. So with me being weird I watched the back story of this song. So here you go.
Trè was masutrbating in his room with headphones on, a pair of girl's underpants on his head and he couldn't see anything. By the time he was done his mom had come into his room and put his dinner at the end of his bed. And he said, 'The funny part is, I wasn't all by myself.'
Well there you go
