In The Last Kingdom, Uhtred receives the nickname «Arseling,» and the meaning behind it is more than just comic relief. The Netflix series follows the fictitious protagonist Uhtred (Alexander Dreymon) in his struggled effort to reclaim his birthright of Bebbanburg during the formation of England in the Middle Ages.

No historical account supports this placement as it's inconvenient to draw a properly proportioned longsword from the back. Since Uhtred is wearing his sword incorrectly, the show's writers intentionally point this out by having Leofric use the word as an insult.
