Pudding-brain

"Pudding-brain" was a Time Lord term used to insult more primitive species, such as humans.

The Doctor, in his twelfth incarnation, used this term against the people in the Victorian era when he thought they were the ones who burned and killed a female Tyrannosaurus rex dinosaur that was rampaging around London, scared and alone. He called Earth the "planet of the pudding-brains". (TV: Deep Breath
