From what I have read in the book "Hammer of the Gods" most of the songs and lyrics in Zeppelin's second album were inspired by the experiences they had on their first American tour. This particular song was allegedly inspired by an aging groupie that particularly annoyed Jimmy Page by showing up to their recording sessions in a New York studio and claiming to have "been" with Page in front of the other groupies. She was in her thirties but had dyed blond hair and dressed provocatively. Anyway, the song is about older women trying to stay young and work it.
