"supercalifragilisticsexwiththeactorofmarypoppinsfan" is the term used to describe somebody who wants to have sex with Julie Andrews a lot, regardless of how old she is. This may seem weird and specific but to them it's totally normal. Though they are seen as one large group, they consist of various smaller groups that add other specifications, such as positions or location of where it happens. However, the most common group you will find prefer Julie Andrews to be in a cat costume. Crazy, I know.
