AFAIK, yes. I read it first in The Dinosaur Heresies, and never again anywhere else. It would probably still be as good a colloquial name for terrestrial high-ish metabolic rate pseudosuchians as any, if there actually _were_ alternatives to it.
I don't think anybody but Bakker was ever interested in coining colloquial names, which is a shame, because the sheer weirdness of prehistoric animals really lends itself to it. Plus, it's useful to have non-scientific names for big animal families where the taxonomy is still screwy.
