(rolling) walker / rollator rock [noun] [de rollatorrock]
By walker/rollator I mean one of those support racks with wheels that old people use to walk around.
As far as I know, this word was introduced a couple of years ago by a Dutch DJ, and it is used to ironically describe rock/pop music by bands that consist of mainly elderly people (or almost elderly).
