Real citation: "Although the world’s Cardinals agreed that Benedict’s less than sporting response to his dismissal was rather undignified, they have forgiven him on the grounds that such unpopely behaviour is not sufficient cause for stripping a Cardinal of his feathers."
(Dale Petrie, 2005, http://www.utterpants.co.uk/news/world/cliffpope.html)
Made-up citation: "White robes are popely; purple thongs are unpopely."
