Tropical Cowboy
A person (commonly a paleontologist or other scientist with odd fashion senses) who wears an unusual mixture of clothing, particularly a Hawaiin shirt with a cowboy hat and corduroy pants. Ironically they travel to many Arctic places, tropical places and other places (see the Nova special on Arctic Dinosaurs).
"I just love reading those scientific journals about dinosaur bones. Carl would be my tropical cowboy dream date."
