An ancient Old Low Franconian (or Dietsc) word for buttocks, ass, backside. This lineage is reflected in related words in other
Germanic languages such as Dutch aars and German Arsch. This word has also been used in the
Norwegian language referring to a creature created by the god of mischief Loki. In an old Norwegian tale, the god of mischief Loki birthed a creature called Aarush. This was a eight legged horse similar in appearance Sleipnir (the infamous horse rode by Odin to travel the nine realms), except this horse never ran or did anything useful for it's legs were like hard rubber and could not bend. Loki replaced Sleipnir with this abdominal creature to offend and delay Odin, who wanted to journey to Jötunheimr. This term has been used as a slang word for people who are seen to be
incompetent and are a liability to those around them.
