went out with the dinosaurs
To be unfashionable. "Fila trainers went out with the dinosaurs." When applied to people, such as in the phrase, "Kim Wilde went out with the dinosaurs," this can create a strange image of Kim Wilde briefly dating a Stegosaurus. This was my first interpretation of the phrase, and led to confusion when it was applied to trainers, coats, and television programmes.
Either I'd got it wrong, or dinosaurs would fuck anything.
