The Colour of Magic  - Terry Pratchett

Picturesque. That was a new word for Rincewind the wizard [...]. Quaint was another one. Picturesque meant - he decided after careful obbservation of the scenery that inspired Twoflower to use the word - that the landscape was horribly precipitous. Quaint, when used to describe the occasional village through which they passed, meant fever-ridden and tumbledown.

Twoflower was a tourist, the first ever seen on the discworld. Tourist, Rincewind had decided, meant "idiot".
