Sawyer calls Frank "Yahoo". This comes from the book Gulliver's Travels, published by Jonathan Swift in 1726. The Yahoos are vile and savage creatures, filthy and with unpleasant habits. They're primitive creatures that represent the distasteful materialism and ignorant elitism Swift encountered in Britain. Hence the term "Yahoo" has become synonymous with "cretin," "dinosaur," and/or "Neanderthal."
