Made famous by Shawn Spencer of Psych, "jujumagumbo" is something that is completely extreme! Most often used in negative context, it can, however, be either good or bad. When it is used negatively, it is often preceded by "dark" or similar adjectives. Used in a positive way, it should follow "awesome", "amazing", etc.
That's some dark jujumagumbo! (Negative, obviously)
