A mythical sexually transmitted disease rumored to be in actual existence. It was created cerca 2003 when a manwhore of a student, nicknamed Dejo, from Eastern Oregon University slept with an equally whorish Mongolian exchange student. The two slept with an uncountable, yet enviable, number of other students and it spread like wildfire. No actual medical symptoms exist, however the social consequences are devastating, if not life lasting. The Dejo has been confirmed in at least 7 western states, and is now in Europe and Asia.
"So Jaime banged The Mongol, and then Valerie, who gives it to Landon, who spread it to Singo, and The German Chick too. Which means all of Boise definetly has it and possibly Germany too. Dude, I'm so glad I didn't get The Dejo".
