(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).

Examples:
1. Ga je naar de Rolling Stones?? Dat is toch rollatorrock man!
(“Are you going to see the Rolling Stones?? Man, isn’t that rollatorrock!”)

2. Deze radiozender draait te veel rollatorrock.
(“This (broadcasting) station plays too much rollatorrock.”)
