Homer (word)

Homer is when you accidentally do something resulting in an act that had positive consequences.

History
When Homer Simpson saved Springfield from a nuclear meltdown, (by doing eeny meeney and selecting a button at random), he becomes a hero. Eventually, everyone found out that he was a fraud and that it was luck that saved them. Therefore, Homer became a word. It is used to describe all sorts of luck (such as Barney falling off a chair and finding a pretzel).
