Apparently, in the movie Idiocracy (which I haven’t seen) there was an energy drink called Brawndo: The Thirst Mutilator. Adam Lisagor, filling in for Jason Kottke, says that someone’s actually going to be making Brawndo as a real-world product.
Chris reminded me that this isn’t the first product to have escaped into reality from the world of fiction. The Holiday Inn hotel chain was named after a 1942 movie, and the Bubba Gump Shrimp Company restaurant chain comes from Forrest Gump.
I propose that we call such products tlonian, after the Borges story “Tlön, Uqbar, Orbis Tertius”. (I was going to suggest tertian, but that’s already a term in music theory.) Uqbar itself, a browser being developed for reading Project Gutenberg e-texts, is one such.
