Like the more common "soccer mom", the Rocker Mom will push her kids to succeed in the profession of her broken dreams. Namely, they expect you to be a rock star so they can bask in your glory vicariously.
Often seen trawling gigs still trying to dress like Kate Bush and talking to your friends like, "whoa, maaaaannn!!!".
Jamie's got a Rocker Mom. She's a total milf, but probably too old to wear that much latex.
