A tourist is humanoid. It is an omnivore.
The road from Ankh-Morpork to Chrim is high, white and winding, a thirty-league stretch of potholes and half-buried rocks that spirals around mountains and dips into cool green valleys of citrus trees, crosses liana-webbed gorges on creaking rope bridges and is generally more picturesque than useful.
Picturesque. That was a new word to Rincewind the wizard (BMgc, Unseen University failed). It was one of a number he had picked up since leaving the charred ruins of Ankh-Morpork. Quaint was another one. Picturesque meant-- he decided after careful observation 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".
