I think one of the sources might have been the very funny fic by SectoBoss: 'Fear and Loathing in Kastrup' which yes, is riffing off Hunter S. Thompson. If you haven't read it, do - I think it would appeal to your warped sense of humour. It certainly tickled mine!
For the rest, there were things in the art thread.....I blame Laufey and Feartheviolas. Laufey as a consequence seems to have acquired the sobriquet of 'majestic penguin accordion troll'. It has fangs, or tusks, or.....something. There were probably elements that derived from doodleordie and the chat, which I can't speak to, because both of those move too fast for my limited perceptions.
I believe Haiz may also have been involved? And somebody in the art thread, I don't remember whom, drew the crew on coffee. That may have inspired the fic....or was it the other way around?
Beyond that I, like you, would be grateful for further elucidation.
