A douchebag of high douchebaggery in the feudal world that often kidnaps a princess(of his own kingdom) instead of saving one. In the modern age though, a sir douchebag just has extremely douchebaggy-like qualities, but higher than that of a regular douchebag and lower than that of prince douchebag.
Douchebag: Okay, I beat up those first graders and took their lunch money so that way I could afford enough money to buy an Xbox One and show off my wealth with it even though the PS4 runs more powerful at a lower price.

King Douchebag: Good, I now promote you to sir douchebag!
